What is asynchronus and synchronous counter?
Asynchronous counter means that the output can change without any relationship to the inputs. synchronous means that the output will only change in sync withe input like a rising clock or a falling clock transition, Read More »

1. Easier to design 2. No propagation delay Actually the second one is the most important reason. In designing circuits that work at high clock rates, ripples will result in errors so synchronization is very very important. Read More »

in synchronous counters there is no seperate clock for flip flops. out put from one flip flop is given as clock for the next one. for asynchronous seperate clock is needed for operation. Read More »

Synchronous digital circuits will change state only on a clock edge. Asynchronous digital circuits can change state at any time. Asynchronous circuits design is more complex as one must take the possibility of race conditions into account. ...

Asynchronous ripple counters are notorious for letting glitches interfere with count, as each stage is dependent upon the previous stage reaching count and providing an output that will cause it's change. Synchronous counters, on the other ...

You just presented a 4 BIT synchronous binary counter. A two bit counter would have 4 STATES. So it could be called a 4-STATE synchronous binary counter. But I don't know what a 4-stage synchronous binary counter is.

The JK flip-flop can operate as: 1. a Delay (D) flip-flop for shift register applications with JK=10 or 01, usually synchronously clocked or for asychronous latching circuits 2. a Toggle (T) flip-flop for counter applications with JK=11 (ca...
