| Abstract: | A new method of multifrequency fault diagnosis for analog circuit is presented in this paper. This method based on modified nodal approach is easy to set up the fault diagnosis equations and has lower degree of nonlinearity and regular Jacobi matrix form. According to the features of fault diagnosis equations, damping Gauss-Newton method is adopted to solve the equations. Several examples are given to verify the mothod. |
