Band of frequencies adjacent to the carrier. Modulation of the carrier creates sidebands. The sidebands contain the signal data, but consume bandwidth beyond what the carrier needs. In some cases, circuitry may suppress duplicate sidebands without harming the signal data. For instance, AM becomes single sideband when circuits delete one of two identical AM sidebands. Some single sideband equipment also suppresses the carrier frequency. The carrier must then be restored at the receiver before the signal can be demodulated, that is, recovered.
Set of frequencies which are produced on either side of the carrier signal as a result of the modulation process. [Upper sidebands (USB) are higher in frequency than the carrier; lower sidebands (LSB) are below the frequency of the carrier. Various modulation techniques make use of one or both of the sidebands.] ignal - An intentional introduction of energy onto a communications path, resulting in the transmission of information. Contrast with noise.
Either of the two bands of frequencies, one just above and one just below a carrier frequency, that result from modulation of a carrier wave.
a partial, a sine like frequency that is a component of a sound, which is not in tune with the normal harmonic spectrum
A signal equal to the bandwidth of the modulating frequency found above and below the carrier frequency in an AM signal.
A signal either above or below the carrier frequency, produced by the modulation of the carrier wave by some other wave.
A band of frequencies just above or just below a carrier frequency, produced by modulation of a carrier wave.
The bands of frequency above and below a carrier frequency that are produced by its modulation.
The frequency band on either the upper or lower side of the carrier frequency band within which the frequencies produced by the process of modulation fall. Various modulation techniques make use of one or both of the sidebands, some of which also suppress the carrier frequency.
Frequencies distributed above and below the carrier that contain energy resulting from amplitude modulation. The frequencies above the carrier are called upper sidebands, and the frequencies below the carrier are called lower sidebands.
In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, containing energy as a result of the modulation process. While all forms of modulation have sidebands by definition, it is most commonly discussed in amplitude modulation (AM).
