Question

Please explain in detail and use MATLAB code. Thank you.

Prob. 4-1 FM and PM are, respectively, defined as FM: A cos ((t) PM: A cos (kpm(t)) The FM and PM coefficients. kf and kp are kf-100 and kp-2, respectively. The carrier frequency is 400 Hz (1) Plot both the time-domain and frequency-domain representation for two independent message signals, m1(t) and m2(t) using MATLAB. Figure 1 is, again, the illustration of the Rectangular pulse (a) Tn1(t) = 11(t _ 0.5) _ 211(t-1.5) + 411(t-2.5) (b) "12(t) = sin(10??) 1 | 11 ) l | ? (x) 0 0 2 2 2 Fig. 1: Rectangular pulse (2) [FM and PM Modulation] Plot the modulated signals for message signals m (t) and m2(t) in the time domain, and plot the corresponding spectra in the frequency domain using MATLAB (3) [Demodulation] Plot the demodulated signals for both message signals m1(t) and m2(t) in the time domain, and plot the corresponding spectra in the frequency domain using MATLAB
