ABSTRACT:
A unit transformation circuit transforms three discrete input signals into a set of transform coefficient signals characteristic of a "collapsed" Walsh-Hadamard transform. The unit transformation circuit includes two tiers of arithmetic networks. In the first tier, a pair of arithmetic networks generates (A) first sum and difference signals from the first and second input signals and (B) second sum and difference signals from the second and third input signals. Arithmetic networks in the second tier generate a set of coefficient signals from (A) the sum of the first and second sum signals (B) the sum of the first and second difference signals and (C) the difference between the first and second difference signals. The unit transformation circuit forms a fundamental circuit element from which more complex circuits are constructed capable of transforming larger numbers of discrete input signals.
