5 Draw the voltage spectrum of AM wave when one modulating signal is involved.
6 Define Single sideband suppressed carrier AM.
7 What are the advantages of DSB transmission?
8 Mention the use of Envelope Detector.
9 Compare AM and FM.
10 Let Vm(t)=sin(2𝜋X2000t) be the information signal and Vc(t)=5sin(2𝝅X10 6t) be the carrier signal. Calculate Modulation Index.
11 Define angle modulation.
12 Compare NBFM and WBFM.
13 State Carson’s rule for Bandwidth of FM wave..
14 Define instantaneous frequency deviation.
