Gateless Synchronous Counters with J-K Flip-flops

  • R. M. M. Oberman


J-K flip-flops can be interconnected in a variety of ways so that counters can be obtained operating in various cycle lengths. These counters can be synchronous as well as asynchronous in their operation. Since practically all cycle lengths can be obtained with synchronous counters of the type mentioned, the design of gateless asynchronous counters with J-K flip-flops will be left out of this discussion.
