Answer / rishimishra

VSB-SC(VESTIGIAL SIDE BAND SUPRESSED VARRIER)...

Answer / raghavendra prasanna

In tv transmission both the techniques are used i.e AM AND FM.
Amplitude modulation is used for picture portion and Frequency modulation is used for audio portion

Answer / sudesh m.s

mainly VSB type of modulation is used...by the
classification we can say that for audio signal frequency
modulation is used and for video signals amplitude
modulation is used .

Answer / frank

are these answers being given by people who studied telecom
or not?

Answer / rajesh pogula

VSB

Answer / dibyasree dasgupta

Tv transmission makes use of FM for transmitting audio signals(voice)whereas it uses AM for transmission of video signals..
TV transmission generally consists of three basic steps:

Modulation->VSB filtration->Transmission

since in a VSB only a portion or 'part' of one of the sidebands(generally LSB) is filtered and processed, it allows the video signal(contained in USB)along with the audio signal contained in the remainder of LSB to be transmitted at the same time which allows the various programs to be broadcasted through channels...
Thus VSB transmission plays a vital role in TV transmission.

Answer / guest

amplitude modulation

Answer / jitesh kumar

AM is used for video transmission and FM is used for audio transmission

Answer / sacchidanand teke

V.S.B. is the type of TV Modulation and V.S.B meance
vegestial side band modulation ....
In Modulation,
we can also use two types AM AND FM
*AM is used for video and
*FM is used for audio
