Correlation-based comparison of analog signatures for identification and fault diagnosis
Dimitris K. Papakostas, Alkis A. Hatzopoulos · IEEE Transactions on Instrumentation and Measurement · 1993
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.>
