Abstract :
Automatic fault diagnosis and circuit identification using analog signatures are considered, focusing on the automatic comparison of nearly similar analog signatures. Two known correlation-based similarity criteria are compared, and a new criterion using a weighting factor, which improves the discrimination capability, is introduced. Comparative results for various signatures are given, and useful applications of this work are discussed
