11-3) similar to Lathi & Ding, Prob. P.6.8-1 Consider the carrier modulator shown in the figure below, which transmits a binary carrier signal. The baseband generator uses polar NRZ signaling with rectangular pulses. The data rate is 8 Mbit/s. (a) If the modulator generates a binary PSK signal, what is the bandwidth of the modulated output? (b) If the modulator generates FSK with the difference fel - fco = 6 MHz (cf. Fig 6.32c), determine the modulated signal bandwidth. Binary data source Baseband signal generator Modulated output Modulator N-E---
