Chapter 7 Single-SidebandModulation(SSB) andFrequency ...
user.eng.umd.edu• In single-sideband(SSB) modulation only the upper sideband or the lower sideband is transmitted. Thus, SSB modulation requires half the bandwidth of AM or DSBSC-AM modulation. • We will assume that the baseband message signal m(t) is band limited with a cutoff frequency W which is less than the carrier frequency ωc. Then the required ...

Single Sideband Modulation (SSB) - Ryerson University
www.ee.ryerson.caSingle Sideband Modulation (SSB) Standard AM and DSB-SC techniques are wasteful of bandwidth because they both require transmission bandwidth of 2B Hz, where B is the bandwidth of the baseband modulating signal m(t). In both cases the transmission bandwidth (B T) is occupied by the upper sideband (USB) and lower sideband (LSB). Observations
