convolution_show.m – This script generates a series of plots to graphically illustrate the discrete convolution between an impulse response and an input signal to compute the output. freqres.m – This script plots the frequency response and impulse response for a system with a Z-transform given by H(z) = 1 / (1 - .5*z^-1).

y = cos (2*pi*220*t + pi/3); z = cos (2*pi*440*t + pi/6); x, y, and z are arrays of numbers that can be used as audio samples. pi/3 and pi/6 represent phase shifts for the 220 Hz and 440 Hz waves, to make our phase response graph more interesting. The figures can be displayed with the following:

To apply a filter to a 1-D audio waveform, Matlab provides function filtfilt, which takes as arguments the result [b, a] from butter, the waveform, and a value denoting the order (number of coefficients) of the filter. A filter's frequency response can be plotted using function Magnitude values at zero dB are unaffected by the filter.
