signal has the form u(t) = 100 cos[27 f.t +4 sin 27 fmt] %3D where f. = 10 MHz and fm = 1000 Hz. 1. Assuming that this is an FM signal, determine the modulation index and the transmitted signal bandwidth. 2. Repeat part 1 if fm 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.
