Each transponder is recognized by its beacon. The Indian transponder has an unmodulated carrier on 145.940 MHz. The Dutch transponder is modulated with telemetry information on 145.860 MHz. Both are linear transponders offering the CW, SSB and FM modes of amateur radio communication.

Carrier leakage is interference caused by cross-talk or a DC offset. It is present as an unmodulated sine wave within the signal's bandwidth, whose amplitude is independent of the signal's amplitude. See frequency mixers, to read further about carrier leakage or local oscillator feedthrough.

|
Morse code is usually sent using on-off keying of an unmodulated carrier (Continuous wave). No special modulator is required. This interrupted carrier may be analyzed as an AM-modulated carrier. On-off keying produces sidebands, as expected, but they are referred to as "key-clicks".
|
|
As with other modulation indices, this quantity indicates by how much the modulated variable varies around its unmodulated level. It relates to the variations in the phase of the carrier signal: : h\, = \Delta \theta\,, where \Delta \theta is the peak phase deviation. Compare to the modulation index for frequency modulation.

The tubes' source (driver) and load (antenna) were split and combined through +90 and −90 degree phase-shifting networks as in Doherty's amplifier. The unmodulated radio frequency carrier is applied to the control grids of both tubes, and with the same control grid bias points. Carrier modulation is applied to the screen grids of both tubes, but the screen grid bias points of the carrier and peak tubes are different and are established such that the peak tube is cut off when modulation is absent and the amplifier is producing rated unmodulated carrier power and both tubes are conducting and each tube is contributing twice the rated carrier power during 100% modulation as four times the rated carrier power is required to achieve 100% modulation.

Soundwave was performed by Frank Welker, whose voice was heavily modulated by a vocoder to achieve Soundwave's distinctive, metallic monotone. However, Welker's voice was left unmodulated at certain points during the episodes "Roll for It" and "Webworld" due to production errors. This left him sounding like Dr. Claw, another role Welker performed, from Inspector Gadget.

This is followed by 3- or 4-minute intervals of 25.1, 25.5, 23.0 and 20.5 kHz of unmodulated carrier precisely phase-locked to UTC(SU) time scale. No time code is sent during the last quarter of an hour.

Steel structure of Duga-1 from below To combat this interference, amateur radio operators attempted to jam the signal by transmitting synchronized unmodulated continuous wave signals at the same pulse rate as the offending signal. They formed a club called The Russian Woodpecker Hunting Club. Core group members would frame the "Official Practice Target" in their radio shacks.

|
Subtle jamming is jamming during which no sound is heard on the receiving equipment. The radio does not receive incoming signals; yet everything seems superficially normal to the operator. These are often technical attacks on modern equipment, such as "squelch capture". Thanks to the FM capture effect, frequency modulated broadcasts may be jammed, unnoticed, by a simple unmodulated carrier.

The panel is in good condition apart from a break to the upper left side. Its size has never been altered, as indicated by a narrow unpainted border on all four sides. The background was thinly overpainted with unmodulated black, probably between 1830 and 1870, when the damaged corner was restored. Eugène Delacroix was suggested to have painted the background.

Roberts, p. 54. He developed early in his career and continued throughout his life to elaborate a highly personal style, with boldly contrasting, jewel-like colors, and flattened, pattern-like forms rhythmically arranged on a canvas. Forms were radically simplified and presented in flat areas of bright, unmodulated color. His paintings have been aptly described as tapestry-like or resembling mosaics.

This way any (unmodulated) radiation emitted for example by the atomizer can be excluded, which is imperative for LS AAS. Simple monochromators of the Littrow or (better) the Czerny-Turner design are typically used for LS AAS. Photomultiplier tubes are the most frequently used detectors in LS AAS, although solid state detectors might be preferred because of their better signal-to-noise ratio.

In the superheterodyne, the radio frequency signal from the antenna is shifted down to a lower "intermediate frequency" (IF), before it is processed. Terman, Frederick E. (1943) Radio Engineers' Handbook, p. 636-638 The incoming radio frequency signal from the antenna is mixed with an unmodulated signal generated by a local oscillator (LO) in the receiver. The mixing is done in a nonlinear circuit called the "mixer".

Phillips, Vivian 1980 Early Radio Wave Detectors, p. 172-185 The radiotelegraphy signals produced by spark gap transmitters consisted of strings of damped waves repeating at an audio rate, so the "dots" and "dashes" of Morse code were audible as a tone or buzz in the receivers' earphones. However the new continuous wave radiotelegraph signals simply consisted of pulses of unmodulated carrier (sine waves). These were inaudible in the receiver headphones.

W.L. Everitt, p. 434 The allowable peak 100% modulated input signal voltage is limited to the magnitude of the bias voltage, corresponding to an unmodulated carrier peak voltage of half the bias voltage magnitude. Either fixed bias or cathode bias may be used for the plate detector. When cathode bias is implemented, a capacitor of low impedance at the carrier frequency and high impedance at audio frequencies bypasses the cathode resistor.

His work gave a face to lower-class figures by infusing their images with recognizable and vividly expressed human emotions—anger, joy, pain, and pleasure. His Youth Making a Face (c. 1632/1635, National Gallery of Art) shows a young man with a satirical and mocking gesture which humanises him, however uninviting he may appear. Brouwer's vigorous application of paint in this composition, with his characteristically short, unmodulated brushstrokes, increases the dramatic effect.

Ground-penetrating radar uses a variety of technologies to generate the radar signal: these are impulse, stepped frequency, frequency-modulated continuous-wave (FMCW), and noise. Systems on the market in 2009 also use Digital signal processing (DSP) to process the data during survey work rather than off-line. A special kind of GPR uses unmodulated continuous-wave signals. This holographic subsurface radar differs from other GPR types in that it records plan-view subsurface holograms.

Plot of signal intensity versus time fitted with a Gaussian function. The string 6EQUJ5, commonly misinterpreted as a message encoded in the radio signal, represents in fact the signal's intensity variation over time, expressed in the particular measuring system adopted for the experiment. The signal itself appeared to be an unmodulated continuous wave, although any modulation with a period of less than 10 seconds or longer than 72 seconds would not have been detectable.

His early paintings until 1964 used oil on canvas, switching then to the new acrylic paints. He generally applied paint in a flat and unmodulated way using masking tape to delineate clear areas of colour. He was an early exponent of the shaped canvas and also produced a small number of 3D and relief works. Reoccurring motifs and elements within his paintings included grid-like forms composed of vertical, horizontal or diagonal lines.

Every BTS dedicates a significant amount of output power to a pilot channel, which is an unmodulated PN sequence (in other words, spread with Walsh code 0). Each BTS sector in the network is assigned a PN offset in steps of 64 chips. There is no data carried on the forward pilot. With its strong autocorrelation function, the forward pilot allows mobiles to determine system timing and distinguish different BTS's for handoff.

The primitive spark gap transmitters used until 1920 transmitted damped waves, which had very wide bandwidth and tended to interfere with other transmissions. This type of emission was banned by 1930. The vacuum tube (valve) transmitters which came into use after 1920 transmitted code by pulses of unmodulated sinusoidal carrier wave called continuous waves (CW), which is still used today. To receive CW transmissions, the receiver requires a circuit called a beat frequency oscillator (BFO).

TDOA-TDOA geolocation is performed, generally, by measuring DTO values using two secondary satellites, or three total satellites. By doing this, two TDOA lines are generated, hopefully, with a crossing point. TDOA – TDOA geolocation is ideal for moving targets, since the movement of the target will introduce varying and random frequency changes, causing an FDOA result to be useless, unless obtained from a highly inclined satellite. TDOA-TDOA geolocation will not work for unmodulated signals.

Two biomechanical features can trigger these traveling wave patterns, which are a low fundamental frequency and in the vocal folds, increasing longitudinal tension. At Amboseli, several different infrasonic calls have been identified. A greeting rumble is emitted by members of a family group after having been separated for several hours. Contact calls are soft, unmodulated sounds made by individuals that have been separated from their group and may be responded to with a "contact answer" call that starts out loud, but becomes softer.

In forward-detected SRS, the modulated laser is blocked by a high OD notch filter and the other laser is measured by a photodiode. Modulation transferred from the modulated laser to the originally unmodulated laser is normally extracted by a lock-in amplifier from the output of photodiode. In epi-detected SRS, there are normally two methods to detect the SRS signal. One method is to detect the back-scattered light in front of the objective by a photodiode with a hole at the center.

Vasko Lipovac (14 June 1931 - 4 July 2006) was a Croatian painter, sculptor, printmaker, designer, illustrator and scenographer and one of the most prominent artists of the region. He is best known for his minimalist figuration and use of intense, unmodulated and often dissonant palette. With the exception of his juvenile period of geometric abstraction, he remained loyal to figuration throughout his whole career. Exceptionally prolific, he worked in various techniques and was equally skilful in using high-polished metal, polychromous wood, enamel, terracotta or polyester to create his sculptures, reliefs and mobiles.

Iosif Iser (21 May 1881 – 25 April 1958; born and died in Bucharest) was a Romanian painter and graphic artist. Born to a Jewish family, he was initially inspired by Expressionism, creating drawings with thick, unmodulated, lines and steep angles. After studies in Munich and Paris (with, among others, André Derain), Iser worked for the socialist press (Facla and the original version of Adevărul), publishing a large number of caricatures (most of them satirising the Romanian Monarchy). He also started his first series of paintings with Dobrujan themes, usually featuring local Tatar portraits.

In quadrature detectors, the received FM signal is split into two signals. One of the two signals is then passed through a high-reactance capacitor, which shifts the phase of that signal by 90 degrees. This phase-shifted signal is then applied to an LC circuit, which is resonant at the FM signal's unmodulated, "center," or "carrier" frequency. If the received FM signal's frequency equals the center frequency, then the two signals will have a 90-degree phase difference and they are said to be in "phase quadrature" — hence the name of this method.

The Synchronized Beacon Project (SBP) is an effort to deploy coordinated beacon transmitters on 50 MHz using a one- minute transmitting sequence of PI4, CW, and unmodulated carrier. Since modern beacon transmitters are multi-mode and frequency-agile, beacons that normally transmit on other time-multiplexed modes such as WSPR can take part in the SBP when not transmitting in their primary mode. Beacons alternating between frequencies on the same band should sign CALL/S when transmitting on the SBP frequency to ensure unique entries in band-specific propagation report databases.

According to Cameron, he began his career as an artist in 1969. The artist's early works in the 1970s were "flat, unmodulated fields of color transversed by sketchy cartoon-like drawing". In the early 1980s Cameron's style developed into the "long horizontal and vertical lines of color punctuated by curves, squiggles and free hand geometry" that can be seen in his landscapes today. "The suggestion of trees or horizon is often roughly preserved but the real business of the paintings is the rhythm of line, mass, depth and color".

In contrast the new continuous wave transmitters produced a signal consisting of pulses of continuous waves, unmodulated sinusoidal carrier waves, which were inaudible in the earphones.K. G. Beauchamp,History of telegraphy, IET, 2001 , page 201 So to receive this new modulation method, the receiver had to produce a tone during the pulses of carrier. The "tikker", invented in 1908 by Valdemar Poulsen, was the first primitive device that did this. It consisted of a vibrating switch contact between the receiver's detector and earphone, which was repeatedly opened by an electromagnet.

Injection must be at a minimum of −26dB referenced to the unmodulated carrier. The tone used to modulate the subcarrier is nominally 1200 Hz, but may vary by as much as 800 Hz (400 to 2000 Hz). The ATIS message is sent at a transmission rate of 15 to 25 words per minute and must not exceed 30 seconds in its entire length. The message includes the FCC-assigned callsign of the earth station, its telephone number, a ten-digit serial number, and sometimes other information which is voluntary.

Passthrough was turned off when the RF modulator (typically on TV channel 3 or 4 in North America) was on, as this F connector was originally the only way to send the VCR output to older TVs, until unmodulated composite video and RCA connectors became common. European VCRs did not turn off the passthrough when the unit was on – instead, the VCR added its output as an extra channel (usually 38; it was possible to change the output channel, depending on the model, by turning a screw in the back of the VCR or by selecting an appropriate option in the OSD menu).

After viewing a large exhibition of Islamic art in Munich in 1910, he spent two months in Spain studying Moorish art. He visited Morocco in 1912 and again in 1913 and while painting in Tangier he made several changes to his work, including his use of black as a colour.Review: John Russell, Matisse and the Mark Left On Him By Morocco, NY Times The effect on Matisse's art was a new boldness in the use of intense, unmodulated colour, as in L'Atelier Rouge (1911). Matisse had a long association with the Russian art collector Sergei Shchukin.

Therefore, pulse width constrains the maximum detection range of a target. Pulse width also constrains the range discrimination, that is the capacity of the radar to distinguish between two targets that are close together. At any range, with similar azimuth and elevation angles and as viewed by a radar with an unmodulated pulse, the range resolution is approximately equal in distance to half of the pulse duration times the speed of light (approximately 300 meters per microsecond). Radar echoes, showing a representation of the carrier Pulse width also determines the radar's dead zone at close ranges.

Measurements of microwave power can be made directly, usually with a thermistor based detector and meter. However, these instruments are expensive and a common meter used in measurements with a slotted line is instead a cheaper low-frequency VSWR meter. The microwave power source is amplitude modulated with, typically, a signal which is recovered by the envelope detector in the probe and sent to the VSWR meter. This scheme is preferred to simply detecting the unmodulated carrier directly, which would result in a DC output, because a stable, narrowband, tuned amplifier can be used to amplify the signal.

The color burst consists of a minimum of eight cycles of the unmodulated (fixed phase and amplitude) color subcarrier. The TV receiver has a "local oscillator", which is synchronized with these color bursts. Combining this reference phase signal derived from the color burst with the chrominance signal's amplitude and phase allows the recovery of the 'I' and 'Q' signals which when combined with the Luminance information allows the reconstruction of a color image on the screen. Color TV has been said to really be colored TV because of the total separation of the brightness part of the picture from the color portion.

She surrounded herself and her yard with her work. She couldn't hear very well, but she could say whatever she needed to say with a paintbrush and she had a smile that would melt your heart." - artist and musician Lonnie Holley "... As with all advanced improvisation, Smith's was never an unmodulated, let-it-all-hang-out, instinctual process, but rather a mixing of careful planning with retrospective and prospective painterly performance–an act of looking back (in time or space) and looking forward at the painting. One untitled work contains sequential applications of black paint, then orange, then more black, and then red paint.

According to Trainor, Thomson was not satisfied with the picture, fearing that the flat abstract shapes of the foreground rocks and trees were inconsistent with the atmospheric conception of the background. Thomson's colleague J. E. H. MacDonald felt similarly, describing the painting as "faulty and inconsistent." Curator Charles Hill has noted that the tension arises due to the trunk of the tree being "unmodulated and outlined in a darker colour" and the foreground rocks being blocked schematically, all while the sky and water "are treated with a feathery touch." Despite these shortcomings, he would still write that the painting surges with an energy due to its boldness and directness.

This carrier wave usually has a much higher frequency than the input signal does. The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave (as in radio communication), or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing (as in a cable television system). The term originated in radio communication, where the carrier wave creates the radio waves which carry the information (modulation) through the air from the transmitter to the receiver. The term is also used for an unmodulated emission in the absence of any modulating signal.

All broadcast satellite transmissions see it as the DVB-S Transport Stream. It is usually made up of one or more television channels with accompanying audio, sometimes with additional audio- only or data transmission channels. When that composite data transmission path, asynchronous but formatted data, travels through space as RF, it is usually called DVB-S, DVB-T, or ATSC. But when carried on coaxial cable, unmodulated, it is called an ASI signal. It is a one-way transmission, similar to RS-232 asynchronous data—a stream of raw but formatted zeros and ones—designed to primarily travel through coaxial cable at speeds that range from 6-200 megabits per second.

The first radio transmitter, the spark-gap transmitter, produced a string of damped waves that sounded like a buzz or tone in a radio receiver, so the pulses of radio waves used to transmit Morse code were audible as "beeps" in the receiver. However, the new transmitters like the Goldschmidt alternator generated unmodulated continuous waves, which were inaudible in receivers. To make them audible, the tone wheel receiver used the heterodyne principle to convert the radio frequency to an audio frequency. The tone wheel was a disk with contacts around the rim, spun by a small electric motor, which interrupted the incoming radio signal at a radio frequency rate.

The Nav channels allow for communication between cells over long distances through the propagation of action potentials, whereas voltage-gated (Cav) calcium channels allow for unmodulated intercellular signaling. It has been hypothesized that Nav channels differentiated from Cav channels either at the emergence of nervous systems or before the emergence of multicellular organisms, although the origin of Nav channels in history remains unknown. Porifera either came about as a result of the divergence with Cnidaria and Ctenophora or they lost the function of the gene encoding Nav channels. As a result, Porifera contain Cav channels which allows for intercellular signaling, but they lack Nav channels which provide for the conductance of action potentials in nerve nets.

Self-other differentiation of object representations. Unpublished research manual, Yale University. later developed the Differentiation- Relatedness (D-R) Scale, another method for evaluating self and other descriptions that is more experiential and affective than the CL Scale and that takes into account more severe boundary disturbances at its lowest levels and more sophisticated aspects of intersubjectivity at its highest levels. The D-R Scale has been found to measure the therapeutic transition of borderline patients from descriptions of self and significant others that are polarized and exaggerated, with extreme, unmodulated characteristics, whether positive or negative, to descriptions that begin to integrate contradictory aspects of self or others and that therefore indicate the transition into evocative object constancy.

Now the output from the phase detector will differ from zero, and in this way, one recovers the original signal that was used to modulate the FM carrier. This detection process can also be accomplished by combining, in an exclusive-OR (XOR) logic gate, the original FM signal and a square wave whose frequency equals the FM signal's center frequency. The XOR gate produces an output pulse whose duration equals the difference between the times at which the square wave and the received FM signal pass through zero volts. As the FM signal's frequency varies from its unmodulated center frequency (which is also the frequency of the square wave), the output pulses from the XOR gate become longer or shorter.
|
|
The two signals are then multiplied together in an analog or digital device, which serves as a phase detector; that is, a device whose output is proportional to the phase difference between two signals. In the case of an unmodulated FM signal, the phase detector's output is — after the output has been filtered; that is, averaged over time — constant; namely, zero. However, if the received FM signal has been modulated, then its frequency will vary from the center frequency. In this case, the resonant LC circuit will further shift the phase of the signal from the capacitor, so that the signal's total phase shift will be the sum of the 90 degrees imposed by the capacitor, and the positive or negative phase change imposed by the LC circuit.

The modulation (and therefore the tracking strategy) of the data bits on the L2SF code has recently changed from unmodulated to 250 bit/s burst at random intervals. The L1SF code is modulated by the navigation data at 50 bit/s without a Manchester meander code. The high-precision signal is broadcast in phase quadrature with the standard- precision signal, effectively sharing the same carrier wave, but with a ten- times-higher bandwidth than the open signal. The message format of the high- precision signal remains unpublished, although attempts at reverse-engineering indicate that the superframe is composed of 72 frames, each containing 5 strings of 100 bits and taking 10 seconds to transmit, with total length of 36 000 bits or 720 seconds (12 minutes) for the whole navigational message.

On December 18, 2005, the satellite failed to make an expected contact at 16:20 UTC. An earlier contact had ended successfully at 07:39 the same day with no sign of trouble. Over the following days and weeks, commands were sent "blind" to reset the transmitter, change antennas, and otherwise attempt to re- establish contact with the spacecraft, but no signal (not even an unmodulated carrier wave) was received. Recovery efforts included using different DSN antennas, using non-NASA ground stations in case there was some systematic DSN error, transmitting no commands for several days to trigger a 72-hour watchdog timer, increasing transmit power in case the antenna was badly misaligned, and optical and radar observations of the satellite to check for debris, change in spin rate or change in orbit indicative of a collision or other damage.

Few films have ever so explicitly expressed a political ideology." Thomson, 2007: "A conventional script was written, but when it proved unsatisfactory, Rand took up the task for free – as long as no one messed with her dialogue." Callahan, 2007: "It’s filmed like a silent movie, and as Rand’s ludicrous dialogue keeps coming at you at an unmodulated volume, you start to wish that it was...the whole thing is a silly stacked deck filled with crude, vague ideas, and it cannot be said that Vidor entirely overcomes the problems of the source material." Shaw, 2013: "Rand ensured that this one would do so by negotiating an unprecedented clause in her screenplay contract that mirrored the demands of her protagonist, Howard Roark: she was guaranteed it would be filmed as she wrote it.” Higham, 1972: “Vidor's earlier movies had tended to emphasize the virtues of the common man.

In New York, he continued to develop these structures while also shifting to a thicker, built- up and scraped-down surface application of oil paint and wax (encaustic). By the late-1980s, he achieved his mature style in works like Black and White Cross Encircled by Red (1988), employing a spare lexicon of emblematic forms (crosses, semicircles, squares, rectangles), thick exposed supports, interlocking planes and shaped or assembled canvasses, that he painted in vivid, unmodulated colors with rich, layered surfaces.Kirshner, Judith Russi.

Amateur radio operator transmitting Morse code Wireless telegraphy or radiotelegraphy, commonly called CW (continuous wave), ICW (interrupted continuous wave) transmission, or on-off keying, and designated by the International Telecommunication Union as emission type A1A, is a radio communication method in which the sending operator manipulates a switch called a telegraph key, which turns the radio transmitter on and off, producing pulses of unmodulated carrier wave of different lengths called "dots" and "dashes", which encode characters of text, usually in Morse code. At the receiving location, the code is audible in the radio receiver's earphone or speaker as a sequence of buzzes or beeps, which is translated back to text by an operator who knows Morse code. Although this type of communication has been mostly replaced since its introduction over 100 years ago by other means of communication it is still used by amateur radio operators as well as some military services.Morse code training in the Air Force A CW coastal station, KSM, still exists in California, run primarily as a museum by volunteers,Coast Station KSM and occasional contacts with ships are made.
