Fault diagnosis method of non-linear analog circuits based on Volterra series and SVM

A new fault diagnosis method of analog circuits is proposed in this paper. The method is based on Volterra series and SVM. This paper introduces the basic theory of Volterra series and SVM and deduces the proposed identification method in detail. The identification method is applied to the fault diagnosis of a non-linear analog circuit. The simulation result shows that the proposed method can obviously improve the fault diagnosis rate compared with the traditional method.
