A Fault Diagnosis Algorithm of Analog Circuits Based on Node-voltage Relation

نویسنده

  • Zbigniew Czaja
چکیده

A new method of diagnosis of single faults of passive elements in analog electronic circuits, based on the node-voltage relation approach, is presented. This method consists of two parts: creation of a fault dictionary describing the nominal state of the tested circuit and containing indirect parameters representing respective faults, and a new fault detection and localization algorithm.

Fault Diagnosis of Analog Circuits Using Extension Genetic Algorithm

This paper proposed a new fault diagnosis method based on the extension genetic algorithm (EGA) for analog circuits. Analog circuits were difference at some node with the normal and failure conditions. However, the identification of the faulted location was not easily task due to the variability of circuit components. So this paper presented a novel EGA method for fault diagnosis of analog circ...

Fault Diagnosis of Analog Circuit Using DC Approach and Neural Networks

Several approaches for the diagnosis of faults in analog circuits have reasonably accuracy which comes at the cost of heavier processing requirements and lowered efficiencies. In this paper, we propose a time domain based technique for fault diagnosis using specifications extracted from the step response of a circuit. With the help of neural network we have to go for back propagation learning p...
