Wave that serves as the vehicle for the transmission of information applied to it.
A single-frequency wave that is modulated by another waveform in order to transmit information.
Periodic waveform. A carrier may be modulated or unmodulated. It may also be continuous or switched. Typically, modems modulate the carrier wave with a data signal. Modulation represents the data signal by impressing a variation on some characteristic of the carrier wave. For instance, a circuit may represent the signal as a proportional shift in carrier amplitude, frequency, or phase. Demodulation (detection) eliminates the carrier wave and reproduces the signal. The carrier frequency must be significantly greater than the signal frequency. A modem may simultaneously apply more than one signal and more than one modulation method to the same carrier. The modulation method may suppress the carrier before transmission. In that case, the receiver must reinsert the carrier before demodulation can occur.
Transmitted energy which is modulated in order to carry information. Usually, it is in the form of a radio-frequency sine wave, modulated either in amplitude or in frequency.
The wave that transports the signal wave. The carrier is modulated or altered by the signal wave.
A data-carrying radio signal carried on some medium, in addition to other signals (such as electricity).
a radio wave that can be modulated in order to transmit a signal
a radio-frequency wave that carries information
a waveform (usually sinusoidal ) that is modulated (multiplied) by a signal that is to be transmitted
An electronic signal that is capable of carrying information when the signal is modulated.
The radio wave that's modified to include a signal. In the case of AM transmission, the carrier wave's power is changed, or modulated. For FM broadcasts, the carrier wave's frequency is altered. Stations are assigned a bandwidth for their carrier waves.
The purely sinusoidal component of a complex waveform that carries a signal from a transmitter to a receiver. The carrier wave itself cannot transmit information but must be changed or modulated, two common methods for doing so being amplitude modulation and frequency modulation.
(Wireless) A high-frequency waveform that can be modulated in amplitude, phase or frequency to carry a signal from a transmitter to a radio receiver.
A carrier wave, or carrier is a waveform (usually sinusoidal) that is modulated (modified) to represent the information to be transmitted. This carrier wave is usually of much higher frequency than the baseband modulating signal (the signal which contains the information).
