Why we use vestigial side band (VSB-C3F) transmission for
picture?

Answer Posted / roz

bandwidth of signals used for picture reception is very
large,so standard am cannot be used.if ssb were used,it
would result in half the bandwidth.but,ssb receivers being
compllex,they are not used.so vestigial transmission is used
in which a vestige or trace of the unwanted sideband is
transmitted along with the wanted sideband and carrier.
