Original structure for Walsh–Hadamard transform on sliding window

The Nth-order Walsh–Hadamard transform on a sliding window is described here by means of FIF filters. Factoring the transfer functions of the filters allows for a synthesis of the transform as a tree of comb filters. The trees built in ascending or descending order of the delay value allow the compu...
