The fault detection method for the subcircuits of a cascade linear circuit
is discussed. While there is any fault (either "hard" or "soft" and either
"single" or "multiple") at one subcircuit of a cascade linear circuit, it c
an be quickly detected by using the method proposed in this brief. While th
ere are faults simultaneously existing at multiple subcircuits, they can ge
nerally be detected by the searching approach proposed in this brief. The a
forementioned method is the continuation anti development of the unified fa
ult defection dictionary method for linear circuits proposed in [1].
