1) Let's define an 32-point sequence 1, n = 7, 8, 9, 10 x[n] = = 0, otherwise a) Compute and plot the magnitude of its 2048-point DFT. b) Then import "handel" sound by calling load handel.mat;, you can also listen that sound -sound(y, Fs);. Plot the given audio data and label each axis properly. c) Compute and plot the linear convolution result of audio signal and 31th order filter. d) By using overlap-and-add method obtain the filtered output signal and plot it. You are only allowed to use -fft- built-in function of MATLAB. Please use 2048-point fft while im- plementing this method. e) Compare and elaborate on your results for part (c) and (d).
