Abstract : A Gray code counter is provided having identical modular circuits with each modular circuit providing a Gray code count sequence having a predetermined number of bits and an enable signal to enable a successive modular circuit of the Gray code counter. Each modular circuit of the Gray code counter enables a successive modular circuit only during certain predetermined counts of the Gray code count sequence. The number of modules required to implement the counter is determined by the number of binary bits per module and the total number of binary bits provided by the counter. The Gray code counter can operate either in an up mode count or a down mode count in accordance with the Gray code count sequence.
