The Application of MATLAB and PSpice In the analog circuit Fault Feature Extraction
Abstract:Fault feature extraction counts a lot in the analog circuit fault diagnosis. It influences the system diagnostic capabilities directly. This paper describes the application of MATLAB and PSpice in the analog circuit fault feature extraction. it emphasize on how to call the data of PSpice simulation in the MATLAB, and introduce the specific way to achieve analog circuit fault feature extraction based on multi-resolution analysis and wavelet packet transform.
Keywords: MATLAB PSpice Fault Feature Extraction Multi-Resolution Analysis Wavelet Packet Transform
