Answer / mahesh bhosale
In TV Transmission the use of FM is made for Audio
transmission and AM for Video transmission.
Vestigial Sideband modulation (VSB) is used for the
following reasons :
1. Video signal exhibits a large bandwidth and significant
low-frequency content which
suggests the use of VSB
2. The circuitry for demodulation in the receiver should be
simple and therefore cheap.
VSB demodulation uses a simple envelope detection.
But the practical TV signals are not exactly VSB modulated
due to the following
reasons :
I) The power at the transmitter is very high and it would
be expensive to rigidly control the
filtering of sidebands. Instead, a VSB filter is inserted
in the receiver where the powers are
low.

Answer / sanket patil
VSB i.e. Vestigal Sideband Modulation is usedfor TV
transmission. Vestige means "PART". The part of side band
is used to transmit the video signal and the remaining is
used for transmitting the voice signal.

TV signal consists of audio and video signals. for audio FM
is used and for video AM is used. this is in india.
different countries follow different modulation techniques
for audio and video signals. in india we use PAL system.
thats why we use above said modulation techniques.

Answer / giri babu
In TV Txion, VSB(a form of AM) modulation scheme is used
for transmission of video information and FM is used to
transmit voice/sound information
