| Abstract: | This paper presents three methods of analog AC fault dictionary using BP network in order to provide robust diagnosis of analog fault diagnosis using a simple mechanism. Network of reasonable dimension are shown to be capable of robust diagnosis of analog circuit including effects due to tolerances. White noise method show the specific method for optimally selecting training patterns and white noise generator , a good test signal generator closer to the goal of built - in self - test. In addition, there is a brief presentation of multiple frequencies method. |
