This project is about designing generalized MATLAB codes that perform discrete convolution and discrete-time Fourier transform (DTFT) to audio and voice signals. Signal-processing MATLAB functions ...

% y is the time domain pointwise product of x1 and x2 y = x1.*x2; h1 = freqz(x1, 1, w); % DTFT of sequence x1 h2 = freqz(x2, 1, w); % DTFT of sequence x2 h3 = freqz(y,1,w); % DTFT of sequence y ...
