Assignment:
[PAM Signal Spectrum] In an amplitude-modulated digital PAM system, the transmitter filter with impulse response gy(t) has a square-root raised-cosine spectral characteristic, with a roll off factor α = 0.5. The carrier frequency is ƒc = 40/T. Evaluate and graph the spectrum of the baseband signal and the spectrum of the amplitude-modulated signal.
Provide complete and step by step solution for the question and show calculations and use formulas.
