Application of Discrete Walsh Functions to Digital Filter Techniques.

Methods of generating and properties of Walsh functions are discussed with emphasis on discrete Walsh functons. Hardware and software versions of two methods of Walsh function generation are shown. The Walsh transform is explored and hardware and software realizations of a fast Walsh transforn algorithm, particularly applicable to hardware, is introduced. Computer programs containing the various algorithms are included. A discussion of the feasibility of the use of Walsh functions to produce a digital filter with a desired frequency response is presented. (Author)
