Single-sideband modulation - Wikipedia

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. Amplitude modulation produces an output signal the bandwidth of which is twice the …

Methods of Suppressing Unwanted Sidebands | Filter System

The phase-shift method avoids filters and some of their inherent disadvantages, and instead makes use of two balanced modulators and two phase-shifting networks, as shown in Figure 4-5. One of the modulators, M 1 , receives the carrier voltage (shifted by 90°) and the modulating voltage, whereas the other, M 2 , is fed the modulating voltage (shifted through 90 ° ) and the carrier voltage.

Generation of SSB signals - KFUPM

Generation of SSB signals 1. DSBSC Filtering Method: Since SSB modulation is the transmission of the upper or lower side bands, SSB modulation can be generated by filtering the undesired side band of a DSBSC signal and retaining the desired one using a bandpass filter with bandwidth equal that of the message signal (not twice its bandwidth) and a
