After completing the course, are you able to apply the principle of modulation over Frequency Division Multiplexing (FDM), FM Stereo Multiplexing, and Superheterodyne Receiver?  

For a DSB-SC modulation, if s(t)=m(t)c(t), where m(t) = 2 cos(2π(1000)t) and c(t)=8cos⁡(2π(10000)), then the maximum magnitude of S(f) is

For the given s(t)  s(t)=4 [1+0.5cos⁡(2π(100)t)]cos⁡( 2π(5000)t), if Ka=0.5/V, then the values of Amax and Amin are

For the given spectrum of s(t) if ka=0.5/V, then c(t) and the magnitude of m(t) are

In AM, when |ka m(t)| > 1 for any t, the carrier becomes
