Abstract :
An experiment has been designed to identify faulty subnetworks under a nodal decomposition strategy. It is based on checking the voltage consistency of internal analyzable nodes in analyzable subnetworks. The concept of a minimal subnetwork is used to derive a minimal decomposition algorithm which can be combined with three basic voltage-testing conditions. The approach is applicable to both linear and nonlinear large networks. In the experiment, automatic testing equipment (ATE) is used to diagnose an active low-pass filter. The diagnosis procedure can be quickly completed, and the results have proved its effectiveness
