  1. A carrier wave is a waveform (usually sinusoidal) that is modulated (modified) to represent the information to be transmitted.
  2. A carrier wave is a waveform (usually sinusoidal) that is modulated (multiplied) by a signal that is to be transmitted.
  3. A carrier wave is a radio-frequency wave that carries information. (Web site)
  4. Carrier Wave: A Carrier Wave is a radio wave that can be modulated in order to transmit a signal.
  5. A carrier wave is a transmission wave of a specific frequency that is modulated to carry information.

Carrier Waves

  1. The carrier wave’s amplitude, frequency or other property is made different.
  2. Amplitude modulation means a carrier wave is modulated in proportion to the strength of a signal. (Web site)
  3. Frequency modulation (FM) and amplitude modulation (AM) signals are microwave rf carrier wave both transmitted with the help of carrier frequencies.


  1. In operation, a PSK carrier wave transmitted from the central station 1 (FIG. 1) is received by each satellite station 11 to 18 through its antenna 21 to 28.
  2. The carrier wave is amplified as it goes to the antenna.


  1. In this diagram, the carrier wave is represented by white, the signal wave by fl. (Web site)
  2. Hence the information from a low-frequency analogue signal must be superimposed on a higher-frequency signal (known as a carrier wave) before transmission.
  3. In this system the intensity, or amplitude, of the carrier wave varies in accordance with the modulating signal. (Web site)
  4. But in F.M. the carrier wave is engineered to deliver a uniform output signal. (Web site)
  5. The frequency of the carrier wave is less susceptible to change than its amplitude, so the receiver reproduces the signal more accurately. (Web site)


  1. The term originated because the modulation of the carrier wave is analogous to the fluctuations of the human voice or other sound that is being transmitted. (Web site)
  2. The radio frequency carrier wave of any system is produced by the transmitter as a sine wave. (Web site)
  3. The carrier wave in pulse modulation is a series of pulses all the same amplitude, width and equal spacing.
  4. Broadcast Signals AM radio uses the electrical image of a sound source to modulate the amplitude of a carrier wave.
  5. It consists of a carrier wave with a (theoretically infinite) series of pairs of sidebands. (Web site)


  1. Where Morse code is used to turn the carrier wave on and off, the term used is not 'amplitude keying', but 'continuous wave' (CW) operation.
  2. Amplitude Shift Keying (ASK) is a modulation process which imparts to a carrier wave (sinusoid) two or more discrete amplitude levels.
  3. Frequency shift keying uses the existing carrier wave, say, 879.990 MHz. (Web site)


  1. Synonym: carrier wave.
  2. The frequency for a given radio station is actually the carrier wave's center frequency. (Web site)
  3. Information about carrier wave in Free online English dictionary.
  4. A transmitter sends a modulated carrier wave to the transmitting antenna.
  5. Retrieve the information content from a modulated carrier wave; the reverse of modulate.


  1. GMSK is a phase modulation that converts a serial bit stream into a phase shift of a carrier wave. (Web site)
  2. There are various forms of modulation, each designed to alter a particular characteristic of the carrier wave. (Web site)
  3. Carrier Wave This shows a strictly monochromatic (single frequency) wave (red curve) with no modulation (blue flat line, no markers).
  4. The equation for the carrier wave of frequency --c, taking its phase to be a reference phase of zero, is c(t) = Csin(--ct). (Web site)
  5. Phase modulation has the same net effect as FM, but phase deviation is measured in degrees or radians, compared to the umodulated carrier wave.

Modulation Techniques

  1. The amount of feedback may be controlled by multiplying the amplitude-modulated carrier wave with a predetermined modulation index. (Web site)
  2. The modulation process involves some feature of the carrier wave being varied in accordance with the information transmitted. (Web site)
  3. A modulation technique in which the phase (angle) of a carrier wave is changed according to the baseband signal (information) variations. (Web site)
  4. Phase-shift keying (PSK) is a digital modulation scheme that conveys data by changing, or modulating, the phase of a reference signal (the carrier wave). (Web site)
  5. PSK Phase Shift Keying A broad classification of modulation techniques where the information to be transmitted is contained in the phase of the carrier wave.
