1. In a logic apparatus for performing logic operations on frequency encoded signals, the improvement comprising:

  • means for decoding and encoding optical input and output signals to and from said apparatus, said signals having three frequency components, said means includingfrequency sensing decoding means for sensing the presence or absence of said three frequency components in said input signals and converting said frequency signals to specific electrical binary signals having logic levels indicative of presence or absence of said frequencies;

    a binary logic circuit adapted to accept said electrical binary signals from the decoding means, to perform logic operations on said signals, and to provide an output ensemble of electrical binary signals; and

    frequency selecting encoding means for converting said ensemble of electrical binary signals to output optical signals having said three frequency components whereby there is encoded logic levels of specified ones of said individual binary signals as presence or absence of said frequency components.
