WebSideband Modulation − Disadvantages. The disadvantages of SSB modulation are −. The generation and detection of SSB signal is a complex process. Quality of the signal gets affected unless the SSB transmitter and receiver have an excellent frequency stability. Sideband Modulation − Applications. The applications of SSB modulation are − Web"In radio communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of modulation used to transmit information, such as an audio signal, by radio waves. A refinement of amplitude modulation, it uses transmitter power and bandwidth more efficiently.
