Abstract

PURPOSE: To reduce opportunities for generation of dangerous erroneous outputs, by executing negative and positive logics alternately in time division correspondingly to the high level and the low level of a reference square wave signal and by taking out negative-phase-sequence components of the reference square wave signal out of alternating signals obtained as outputs of logics.
CONSTITUTION: Input signals A, B and C are input to input signal lines 101, 102 and 103 respectively, and output signal D is transmitted from output signal line 104. Here, reference square wave signal X of square wave oscillator 6' by input converters 12...14 so that signals A, B and C may be exclusive OR. In respect to majority OR circuit 15, signal X is given as one of input signals, and circuit 15 operates as an AND circuit corresponding to negative and positive logics of two signals A and B. Next, in respect to majority logic circuit 16, the inversion signal of signal X is given as one of input signals, and circuit 16 operates as an OR circuit corresponding to negative and positive logics of the output signal of circuit 15 and signal C, and the alternating signal having the phase opposite to signal X is taken out. As a result, opportunities for generation of dangerous erroneous outputs can be reduced.
