Consider a AM signal:
φam(t) = ( 1 + A cos ωmt) . cos ωct
where the frequency of the information sinal wm = 5 KHz and the frequency of the carrier wc = 100 KHz. The constant A = 15. That signal may be demodulated by a envelope detector?
What should be the output of the envelop detector?
Find out the frequency spetrum of the envelop detector output.
