CS 601   Like Us On Facebook Question No.1: •          Calculate the bandwidth required of the given AM Station with proper unit. •          Modulating signal with bandwidth of 7 KHz Ans: Bandwidth of AM signal (Modulated signal) = 2*bandwidth of modulating signal (audio). Bandwidth of AM signal (Modulated signal) = 2*(7 KHz)   Bandwidth of AM signal (Modulated signal) = 14 KHz (Bandwidth for an AM station). •          Calculate the bandwidth required of the given FM Station with proper unit. •          Modulating signal with frequencies of 10000 to 19000 Hz.         Ans: Fc1-Fc0 = 19,000-10,000   = 9000 Hz   = 9 KHz            Bandwidth of FM signal (modulated signal) = 10*bandwidth of...
