Abstract : It is one object of the invention, therefore, to provide an improved Walsh transform computer using a recursive algorithm to perform the Walsh transform function which results in a reduction in hardware implementation. It is another object of the invention to provide an improved Walsh transform computer using only N summing junctions where N is the total number of input data samples. It is yet another object of the invention to provide an improved Walsh transform computer wherein a feedback-in-time circuit is used to implement the Kronecker-product rule.
