| Abstract: | The algorithm of BP neural network is analyzed and the analog circuit is simulated by using PSPICE software in this paper. Based on these, the fault dictionary is established, and analog circuit fault diagnosis is realized by looking up fault dictionary. The shortage of BP network in diagnosing fault is pointed out and brought up solution. This solution method improves the automation degree to establish diagnostic model and the accuracy of fault diagnosis. The result is better and value by simulation. |
