Q. Let a(t) = [1 + mAx(t)] and x(t) = cos 2πfmt, fm << fc, and xc(t) = A(t) cos 2πfct .
(a) With mA =1, sketch one full period of the AM wave and draw the envelope by connecting the positive peaks of xc(t).
(b) Repeat part (a) with mA = 2, and notice that the carrier is overmodulated and the envelope does not have the same shape as x(t).
(a) Now consider a typical open-wire transmission line with parameters of R = 14 /mi, L = 4.6 mH/mi, C = 0.01 µF/mi, and G = 0.3×10 -6 S/mi. If the line operates at 1 kHz, find t
