1. Task 3 1-m A certain RF application has transfer function H(z) = 1-2 (m) (cos(0))2-¹+m²z-21 a. Plot the spectrum of sample_pcm.mat (file available on moodle) on a scale (- to π). Use only 100 samples of the file. The sample_pcm.mat is modulated at 3146 Hz and sampled at 8kHz. b. Write a matlab script to implement H(z) assuming m = 0.995 and 0 = peak of the spectrum from part a. Plot the magnitude and phase response of the filter on a normalized frequency scale. c. Filter the signal sample_pcm through the transfer function implemented in part b and compare the spectrum of input signal and filtered signal. d. Use sound function in matlab to demonstrate the working of filter. e. Repeat the procedure for m = 0.9999999 and observe the difference.
