Integer-code DC fault dictionary

This paper addresses itself to computer-aided diagnosis of analog circuits by means of simulation-before-test approach, the so called dictionary approach. New method of dictionary construction is presented. The method combines three previously presented methods, namely: sensitivity based method of finding ambiguity sets in measurement space and corresponding binary signatures, information channel based method of finding minimum set of measurements and a method of the integer-code dictionary formulation, based on the introduced quasi Hamming distance between signatures.
