Question

Please I want the solution of this exercise.

Thanks.

. (10 pts) The binary sequence 1100100010 is applied to a DPSK modulator. The carrier frequency is f 1/T a- Draw the block diagram of the DPSK modulator. b- Sk etch the resulting waveform at the DPSK modulator output (reference bit = 1). SK demodulator of (Fig.2). Show that, in the output, in both c- The waveform (part b) is applied to the DP absence of noise, the original sequence is reconstructed at the demodulator case: θ:= 0 and θ=π/4 Delay Y Decisionn circuit 1 if Y0 -n/2 →| Delay Threshold = 0 Y. dt
