Abstract
Logic expressions are developed for a Walsh function generator for highly-orthogonal sal and cal sequency pairs, using clocked T-type flip-flop outputs. It is shown that the flip-flop toggle logic functions are generated fully by the rate multiplier type 7497, leading to economical implementation. Thus a generator for up to 63 sequency pairs consists of only seven integrated circuits.Keywords
