ball mill fault diagnosis

Fault diagnosis (Chapter 10) - Testing of Digital Systems

The cause-effect diagnosis methodologies follow. In these methodologies, each faulty version of the circuit is simulated, implicitly or explicitly, and its Diagnosis is the process of locating the faults present within a given fabricated copy of a circuit. For some digital systems, each fabricated copy is
