WebMar 27, 2015 · Since the flip flops work synchronously, the synchronous counters do not require settling. There is a required number of logic gates to implement the synchronous counters and the operation is fast. Unlike the asynchronous counter, the synchronous counter has one global clock which drives each flip flop so output changes in parallel. WebFeb 14, 2024 · A J-K flip flop will count (toggle) when both J and K = 1. We can make a free-running counter by just using J, tying K high. To reset Q in a J-K flip flop we must set J=0 and K=1. If we make RESET active low, then the circuit below does that.

I was stuck on this problem for the past week and I couldn't find anything which helps.

Synchronous Counters can be made from Toggle or D-type flip-flops. Synchronous counters are easier to design than asynchronous counters. They are called synchronous counters because the clock input of the flip-flops are all clocked together at the same time with the same clock signal. See more It can be seen above, that the external clock pulses (pulses to be counted) are fed directly to each of the J-K flip-flops in the counter chain and that both the J and K inputs are all tied together in toggle mode, but only in the … See more Because this 4-bit synchronous counter counts sequentially on every clock pulse the resulting outputs count upwards from 0 ( 0000 ) to 15 … See more As synchronous counters are formed by connecting flip-flops together and any number of flip-flops can be connected or “cascaded” together to form a “divide-by-n” binary counter, the … See more WebOct 12, 2024 · The above circuit shows the circuit diagram of a 3-bit asynchronous up counter, in which the clock pulse is given as clock input for JK FF1.
