Vsb has been used for video signal transmission because the video signal having a bandwidth of 0 to 4.5 mhz if we use
Am and dsb then the amount of bandwidth would be 9 mhz(2fm)
Which is practically impracticable . If we use ssb the spectral gap for video signal is o hz and there may lose of information takes palce in ssb.
So vsb has been used
