Question: An angle - modulated signal has the form u ( t ) = lOOcos [ 2 nfct + 4 sin 2 nfmt ] , where

An angle-modulated signal has the form u(t)= lOOcos [2nfct +4sin2nfmt], where fc =10 MHz and f m =1000 Hz.1. Assuming that this is an FM signal, determine the modulation index and the transmitted-signal bandwidth. 2. Repeat Part I if f m is doubled. 3. Assuming that this is a PM signal, determine the modulation index and the transmitted-signal bandwidth. 4. Repeat Part 3 if fm is doubled.
