Abstract

Abstract: The directional graphic of fault propagation is established based on the clock circuit of the broadcasting station and granular reasoning method and directional graphic of fault propagation are unified. The sample sets of the fault are obtained according to the circuit simulation and analysis, after that the sample sets of the fault decision is transformed into decision table which reflects the relation of faults and symptoms, then the decision table is transformed into the corresponding granular based, consequently fault source that most likely occurrence to fault is found by searching granular based and computing the most similarity.
