3. In a QAM receiver using synchronous detection, the local oscillator produces an accurate cosine wave 2cos(x), but the two receiver branches have mismatched lengths, causing a phase delay of -1/(3+N) radians in one branch, as shown. Compute the component of the quadrature channel message appearing in the in-phase output, and compute the component of the in-phase message appearing in the quadrature output. QAM signal Low-pass filter 151(1) (1) 200001 #12 2 sin[)] Ap= Low-pass -л(3+N) filter x2(1) my(1)
