A Higher Radix Technique for Fault Detection in Many-Valued Multithreshold Networks

A technique for fault detection of many-valued multithreshold switching networks is presented. An arbitrary network, implemented with R-valued multithreshold gates, called MT(R), can be transformed into an MT(R + 1) or an MT(R + 2) network which uses additional truth values for fault detection purposes. The technique leads to reduced test sets, which are usually simpler to derive.
