In TV transmission, picture signal is ________ modulated.(a) DSB-SC(b) VSB(c) SSB-SC(d) PulseThis question was posed to me in semester exam.This interesting question is from Transmitter in division Elements of Communication System of Analog Communications

Answer»

Right choice is (b) VSB

For explanation: All ANALOG television systems USE vestigial sideband modulation, which is a form of amplitude modulation, for transmission. In VSB, ONE sideband is fully TRANSMITTED and another sideband is partially removed, which further REDUCES the bandwidth of transmitted signal. This enables narrower channels to be used.
