Please write Matlab code for 4.13-2 which is based of from the first problem.

MPUTER ASSIGNMENT PROBLEMS 4.13-1 Consider a new message signal ()0.125 (100+4u+004)-uG+002)1+0125 (100nlu+002) -u-0.02)]-0.125 (100-4)3u-0.02)-u-0.04) We select carrier frequency to be fe -500 Hz. Following the example in Section 4.12.1, numerically generate the following figures: (a) The signal waveform of m (0) and its frequency domain response. (b) DSB-SC amplitude modulation signal s(t) mi (1) cos 2 and its frequency response. (c) The signal e(t)-2s(t) cos2nfet and its frequency response. (d) The recovered message signal in time and frequency domain. 413-2 Keep the same mi (t) andfe = 500 Hz in Problem 4.13-1. Following the example in Section 4.12.2, numerically generate the following figures: (a) Conventional AM signal s() [1.2 + mi (t)] cos2nfet n time domain. (b) Signal s(t) in (a) rectified without local carrier in time domain. (c) Envelope detector output in time domain.
