Abstract

A numeric value in binary code can be translated into the equivalent value in Gray code by combining the original binary value with the original value shifted to the right one bit position the combining being done by an "exclusive OR' operation. An example follows. Original binary number (a) 0110 (Decimal equivalent : 6) Shifted right one bit position (b) 0110 Exclusive OR function of a (;##) b 0101 (Gray code - Decimal equivalent = 6)
