Problem 7 A communication channel has a bandwidth of 100 KHz. This channel is to be used for transmission of a normalized message signal , where max | | 1, and its bandwidth is W = 4 KHz. Find the ratio of the output SNR of an FM system that utilizes the whole bandwidth to the output SNR of a DSB-LC AM system (of the same carrier amplitude modulation index of 0.8. ) with a...
