%% Polyphase Matrix of Filter Bank
% Compute the polyphase matrix of the filter bank used by the channelizer.
%
% Design a channelizer with the number of frequency bands or polyphase branches set to 8, the number of taps or coefficients per band set to 12, and stopband attenuation set to 80 dB.

channelizer = dsp.Channelizer;
p = polyphase(channelizer)

%
% Each row in the matrix corresponds to a polyphase branch. The number of columns in the matrix corresponds to the number of filter taps per branch.
