Fault Diagnosis of Analog Circuit Based on PSO-WNN

In order to address the problems of the conventional Wavelet Neural Network(WNN) in analog circuit fault diagnosis,a new method of analog circuit fault diagnosis,based on Wavelet Neural Network and particle swarm optimization(PSO-WNN), is proposed in this paper.A practical inspecting of a filter circuit has been implemented,using both the new and the conventional method.The experimental results indicate that the new method possess higher precision than WNN.
