The Largest Amount of Fault Information in Analog Circuit Fault Diagnosis Based on Multisim Circuit Simulation

Electronic equipment analog circuit has high failure rate, factors cause failure are fuzzy, fault diagnosis is complex. This method use Multisim circuit simulation software for band-pass filter circuit simulation and analysis, setting the soft and hard failures to obtain simulation results. Using the largest amount of fault information diagnosis method to seek the greatest amount of fault informative feature groups and determine the failure source. This method of fault diagnosis provides a reference for the measured data.
