Question

Please solve for P4, NOT P3. Use DC offset c = 0, c = 1 and c = 1.5

AM Modulator AM Demodulator m(t) mdemod(t) SAM-DSB-C(t) LPF Х cos2ft cos2nfct Figure 3 P3. For the system shown in Figure 3, sketch the signals m(t), SAM-pse-c (t), and "de mod(t) in the time and frequency domain, assuming m(t)=cos 20nt and that AM- DSB-C is the modulation scheme used with f. = 100Hz. P4. Repeat P3 changing m(t) to a 10 Hz square wave, with amplitude 1
