Synchronous johnson counter
WebSynchronous binary counters have a regular pattern and can be constructed with complementing flip-flops and gates. The C inputs of all flip-flops are connected to a common clock. The counter is enabled with the count enable input. If the enable input is 0 all J and K inputs are equal to 0 and the clock does not change the state of the counter. This inversion of Q before it is fed back to input Dcauses the counter to “count” in a different way. Instead of counting through a fixed set of patterns like the normal ring counter such as for a 4-bit counter, “0001”(1), “0010”(2), “0100”(4), “1000”(8) and repeat, the Johnson counter counts up and then down as the … See more As well as counting or rotating data around a continuous loop, ring counters can also be used to detect or recognise various patterns or number values within a set of data.
