1) Consider the amplitude-modulated signal: SAN (1) = A[1+ucos(0,1)]cos(011) Use MATLAB command and M files to draw the modulated signal and the demodulated signal for below three cases, make sure to use envelope detector command. a. Ac=16v, modulation index=0.22, modulating signal frequency=800Hz b. Ac=16v, modulation index=1, modulating signal frequency=800Hz c. Ac=16v, modulation index=1.85, modulating signal frequency=800Hz Discuss your result in each part.you must show your codes. 2) Consider the frequency-modulated signal: SFX (1) = cos(27 (17+ 4 sin(2.70)] a. Use MATLAB command and M files Plot S(t) versus t for-1 St
