Sideband

The power of an AM signal plotted against frequency.Key: fc is the carrier frequency, fm is the maximum modulation frequency

In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, containing power as a result of the modulation process. The sidebands consist of all the Fourier components of the modulated signal except the carrier. All forms of modulation produce sidebands.
