Figure P4.3-5 10 m(t) -10-3. -10 4.3-6 (a) Sketch the time domain AM signal corresponding to the AM modulation in Prob. 4.3-5. (b) If this modulated signal is applied at the input of an envelope detector, show the output of the envelope detector is not m(t). (c) Show that, if an AM signal Ac[A + m(t)] cos wet is envelope-detected, the output is Ac|A+m(t)|.
