Abstract
An electrical counter including a pair of counter segments connected in cascade. Each of the counter segments has a capacity of two bits and counts in Gray code of 00, 01, 11, 10 and 00 on succeeding pulses to be counted which are applied onto the segment. The second segment includes an AND circuit which is satisfied when the count of the preceding segment is 10 so as to GATE the pulse supplied at that time on to the second segment so that the second segment has its value changed at the same time as the first segment has its value changed from 10 to 00.
