side·band

also side band  (sīd′bănd′)
n.
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.

sideband

(ˈsaɪdˌbænd)
n
(General Physics) the frequency band either above (upper sideband) or below (lower sideband) the carrier frequency, within which fall the spectral components produced by modulation of a carrier wave. See also single sideband transmission
