Signal's autocorrelation characteristic is used for fault detection and the fault detection formula is presented in this paper. The implementation schemes under periodic and non-periodic signals are discussed respectively. The fault detection algorithm is presented at the base of Bayesian Decision and corresponding implementation a scheme. In computer simulation, linear frequency modulated signa is selected. The simulation results confirm that the autocorrelation method is applicable. As the conclusion,this method can apply to electronic equipment built-in self-test and can accomplish on-line fault detection of period signals.
