3. We modulate a 100 Hz signal with a 1000 Hz signal: cos 200лt p(t) We then demodulate the signal as follows: X X cos 2000 t cos 2000 t p(t) BPF d (t) Find the spectra of the modulated signal (t) and the demodulated signal d (t). Indicate magnitudes and frequencies. Find the average power in both the modulated signal and the demodulated signal.
