| Abstract: | The approach of acquiring the soft fault constant eigenvector by using K fault diagnosis is presented in this article,and an improved BP algorithm is put forward. An analog circuit is diagnosed by using BP network and fault dictionary. Finally,simulation results show the improved Algorithm of BP are more feasible and efficient in contrast with the traditional methods. |
