Abstract

PURPOSE:To obtain the logic circuit of decision by majority in which the constitution is remarkably simplified, by constituting the circuit with the gate means selecting the pulse to perform the decision by majority and the shift register taking the output as the timing pulse. CONSTITUTION:The pulse train including 3-bit (A1, B1, C1) to be discriminated for decision by majority and the period T of discrimination by majority and the initial state set pulse taking the content of the flip flops 62 and 63 sampling the specific pulses A1, B1, C1 from the pulse train to the initial state every period T, are given to the input terminals 8, 9 and 10. In this case, when at least 2-bit out of 3-bit of A1, B1, C1 is logically 1, logic 1 appears at the output terminal 13 at least.
