What is the advantage of using a VSB transmission?(a) Higher bandwidth

1.	What is the advantage of using a VSB transmission?(a) Higher bandwidth than SSB(b) Less power required as compared to DSB-SC(c) Lower bandwidth than SSB(d) Both higher bandwidth than SSB and less power required as compared to DSB-SCThe question was asked in quiz.Asked question is from AGC in chapter Receivers & Transducers of Analog Communications
Answer» Right answer is (d) Both higher bandwidth than SSB and less power REQUIRED as COMPARED to DSB-SC To explain I would say: Vestigial SIDE BAND is similar to single sideband (SSB) transmission, in which the second sideband is not completely removed, but is filtered to remove the range of frequencies that are not required. It has higher bandwidth than SSB-SC and less power consumption than DSB-SC.
