Matlab Implementation Of Polyphase Filter

mpling frequency t = 0:1/fs:1-1/fs; x = sin(2*pi*50*t) + 0.5*randn(size(t)); % Initialize output y = []; % Polyphase filtering and downsampling for n = 1:M:length(x)-length(h)+1 % Extract current segment segment = x(n:n+length(h)-1); % Initialize output sa
