Electronic Circuits Diagnosis Using Artificial Neural Networks

When we expect  about something that does not treat as it should be,  we are initiating the  process of diagnosis. Diagnosis is a commonly used activity in our everyday lives (Benjamins & Jansweijer, 1990). Complicated systems are always prone to faults or failures. In the simplest term, a fault is every change in a system that prevents it from operating in the proper manner. We define diagnosis as the task of identifying the cause and location of a fault manifested by some observed behaviour. Basically this is  two-stage process: first the fact that fault has occurred must be recognized – this is referred to as fault detection. That is, in general, achieved by testing. Secondly, the nature and location should be determined such that appropriate remedial action may be initiated
