High-speed gray-binary and binary-Gray code convertors using electro-optic light modulators

A high-speed Gray-binary code convertor (g.b.c.) using electro-optic light modulators, which translates all bits of Gray code into binary code simultaneously, and a binary-Gray code convertor, which translates binary into Gray code, are described. A digital-analogue convertor using g.b.c. is also presented.
