Research on Fault Detection and Localization Technology for Electronic Circuits Based on Signal Processing
Signal processing technology plays a crucial role in the fault detection and localization of electronic circuits.Static detection techniques,such as DC testing and parameter testing,are primarily used for fault detection when the circuit is without signal excitation.Dynamic detection techniques,including logic analysis,time-domain reflectometry(TDR),and frequency-domain analysis,are suitable for real-time fault detection of circuits under signal excitation.Fault simulation techniques,such as fault injection and fault modeling,are used to reproduce and understand fault behaviors.Fault localization methods combine fault diagnosis processes with various techniques,including signal feature extraction and data fusion,effectively improving the accuracy and efficiency of fault localization.
