ABSTRACT:
A Gray code counter employs modules of binary bits to form expressions or numbers. The count is sequenced from one expression to the next by changing only one binary bit in one location of an expression. The Gray code counter can be an incrementing counter or an increment/decrement counter. The counter can operate with expressions of several bits, and employs a minimal number of D type flip-flops and logic gates.
