4.3-4 (a) Sketch the DSB-SC signal corresponding to the message m(t) = cos (b) The DSB-SC signal of part (a) is applied at the input of an envelop detector. Shown that the output of the envelop detector is not m(t), but |m(t)|. Shown that, in general, if an AM signal [A + m(t)]cos is envelop-detected, the output is |A + m(t)|. Hence, show that the condition for recovering m(t) from the envelop detector is A + m(t) > 0 for all t.
