A concept of functional transformation of multivalued switching functions, used to obtain simplified implementations is presented. Given some function f, a transformed function g is generated from f by permuting some or all of the truth values. Then, implementing g and performing a reverse permutation, a simpler implementation for f is obtained. A P matrix technique is given to facilitate determination of the required permutation.
