Abstract
An improved counter wherein consecutively cascaded flip-flops of the prior art are divided into two groups. A first detector produces a first signal in response to a predetermined set of flip-flop states of the first group. A second detector produces a second signal in response to a predetermined set of flip-flop states of the second group. A third detector produces a count output in response to simultaneous existence of the first and second signals. The output from the first group is arranged in phase so that the second signal may be produced before the count output is produced, by applying an inverted output of the first group to the input of the second group.
