Abstract
A plurality of two stage Gray code counters are connected in series to generate a multiple bit pseudo Gray code count C.sub.0, C.sub.1, . . . , C.sub.7. A binary count B.sub.0, B.sub.1, . . . , B.sub.7 is then generated by using the odd subscripted bits C.sub.1, C.sub.3, C.sub.5, C.sub.7 of the pseudo Gray code as the binary count bits B.sub.1, B.sub.3, B.sub.5, B.sub.7 and generating the even subscripted bits of the binary count B.sub.0, B.sub.2, B.sub.4, B.sub.6 by Exclusive ORing the odd and even position counts of each two stage Gray code counter together in Exclusive OR circuits.
