ABSTRACT:
In a control system monitor signals are received from points in the controlled system. The signals are band limited by filters respectively to provide matched band limited signals for correlation by comparison logic to provide failure flag output. The invention is based on the realization that signals in different parts of the system should correlate if suitably conditioned, and that the result of the correlation is indicative of performance.
