Abstract :
An approach to fault identification in analog-discrete (SC and SI) circuits is proposed using test measurement data in discrete-time points. The determination of the changed parameter values of the faulty elements is accomplished by a single direct current analysis of a suitable nonlinear identification resistance model. Models of the basic structural elements, as well as the way of the whole identification model construction, are defined. An example considering the SC-circuit fault identification using the PSpice simulator is presented
