Double-sideband suppressed-carrier transmission — (DSB SC): transmission in which (a) frequencies produced by amplitude modulation are symmetrically spaced above and below the carrier frequency and (b) the carrier level is reduced to the lowest practical level, ideally completely suppressed. In… … Wikipedia
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 … Wikipedia
Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… … Wikipedia

Single-sideband suppressed-carrier transmission — Single sideband suppressed carrier (SSB SC) is a telecommunication technique, which belongs to the Amplitude modulation class.The information represented by the modulating signal is contained in both the upper and the lower sidebands. Since each… … Wikipedia
Pilot signal — In telecommunications, a pilot is a signal, usually a single frequency, transmitted over a communications system for supervisory, control, equalization, continuity, synchronization, or reference purposes. Frequency spectrum of an FM broadcast… … Wikipedia
