Synchronous binary counters

Abstract

The synchronous binary counter was developed after the asynchronous counter and, because it gives less problems in its applications, it has become very important in a very short time. Many different types have already come into being, 4-bit binary, bcd, bq, and other types of decade counters, up-down, all with parallel load. Many of them are commercially available as a one-chip integrated circuit and they are all based on the same principle. However, some of them are implemented with J−K flip-flops, some with T flip-flops, and some with a mixture of R−S and J−K flip-flops.
