| Abstract: | A method of fault diagnosis based on dentification of system is discussed. A arithmetic of determining the fault position by using the method of the wavelet packet analysis is detailedly introduced. The appropriate design of the hardware circuit is shown, and the method adopted in this article is proved to be correct by the experimental data. |
