We have developed an analog circuit fault diagnostic system based on Bayesi
an neural networks using wavelet transform, normalization and principal com
ponent analysis as preprocessors. Our proposed system uses these preprocess
ing techniques to extract optimal features from the output(s) of an analog
circuit. These features are then used to train and test a neural network to
identify faulty components using Bayesian learning of network weights. For
sample circuits simulated using SPICE, our neural network can correctly cl
assify faulty components with 96% accuracy.
