Binary-coded modulo-seven negator

    Research output: Contribution to journalArticlepeer-review


    A circuit consisting of four NOR gates multiplies modulo-seven integers, represented by binary digits on three input lines, by six. In modulo-seven arithmetic, this is equivalent to negation, and the circuit is a negator. Negators, together with standard flip-flops and half adders, yield all primitive components needed for binary-coded modulo-seven linear sequential networks.
