sideband, any frequency component of a modulated carrier wave other than the frequency of the carrier wave itself, i.e., any frequency added to the carrier as a result of modulation modulation, in communications, process in which some characteristic of a wave (the carrier wave) is made to vary in accordance with an information-bearing signal wave (the modulating wave); demodulation is the process by which the original signal is recovered from .....

Those frequency components that are higher than the carrier frequency are know as upper sidebands; those lower are called lower sidebands. The upper and lower sidebands contain equivalent information; thus only one needs to be transmitted. Such single-sideband signals are very efficient in their use of the frequency spectrum when compared to standard amplitude modulation (AM) signals. See radio radio, transmission or reception of electromagnetic radiation in the radio frequency range. The term is commonly applied also to the equipment used, especially to the radio receiver. .....

The upper sideband is the carrier plus modulation, and the lower sideband is the carrier minus modulation, which are mirror images of each other. See single sideband.
