Q1.Vestigial sideband is most commonly used in-
Q2.Direction: The item consists of two statements, one labelled as 'Statement (I)' and the other as 'Statement (II)'. You are to examine these two statements carefully and select the answers to these items using the code given below. Statement (I): A popular method for generating a VSB modulated wave is to use the frequency discrimination method. Statement (II): One of the sidebands is partially suppressed and a vestige of the other sideband is transmitted to compensate for that suppression.
