Question: In Illustrative Problem II, the eight PSK waveforms had a constant amplitude. Instead of the rectangular pulse BT ( t) , suppose that the signal pulse shape is
Write a MATLAB program to compute and graph the M = 8-PSK signal waveforms for the case in which ƒc = 6 IT.
Problem II: Repeat Problem I when the transmitter has a square-root duo binary spectral characteristic.
Problem I: In a carrier-amplitude-modulated PAM system, the transmitter filter has a squareroot raised-cosine spectral characteristic with rolloff factor ex = 0.5. The carrier frequency is fc = 40 / T. Evaluate and graph the spectrum of the baseband signal and the amplitude-modulated PAM signal.
