Synchronous Vs Asynchronous: Explore The Difference Between Synchronous and Asynchronous Counter

A logic circuit is made up of a series of flip-flops that are used to count the number of inputs in the form of negative or positive edge transitions. The counter is classified into synchronous and asynchronous counters. The difference between the synchronous and asynchronous counter can be identified according to the flip-flops that are triggered.

What is a Synchronous Counter?

A Synchronous counter is the counter in which the clock input with all the flip-flops uses the same source and produces the output at the same time.

What is an Asynchronous Counter?

The counters whose output doesn’t depend on a single clock signal. There are different clock signals provided to produce the output called Asynchronous Counters.

S.No.	Synchronous Counter	Asynchronous Counter
1.	In the synchronous counter there are continuous clock input signals with flip-flops used to produce the output.	In Asynchronous counters there are different clock signals used to produce the output.
2.	In the synchronous counter, the operation is faster.	In Asynchronous counter the operation is slower.
3.	Synchronous counter is also known as Parallel counter.	Asynchronous counter is also known as Serial counter.
4.	Synchronous counter produces less error than asynchronous counter.	Asynchronous counter produces more errors than a synchronous counter.
5.	Design of the Synchronous counter is complex.	Design of the Asynchronous counter is simple.
6.	Synchronous counters can work with a flexible number of count sequences.	Asynchronous counters can work with a fixed number of count sequences.
