ABSTRACT:
Signals representative of information bits are converted from one binary code, for example, Gray code, to another binary code, for example, conventional binary, and vice versa, by advantageously employing optical couplers in conjunction with buffer amplifiers. The optical couplers include light emitting diodes and associated phototransistors which are uniquely connected in circuit relationship with the outputs of the buffer amplifiers to effect the desired code conversions.
