What is the difference between synchronous and asynchronous counters

So, due to this, the common clock signal causes the change in the state of each individual flip flop simultaneously. This resultantly leads to no ripple effect thus propagation delay does not exist in this counter.

An asynchronous counter is the one also referred as serial counter as here the flip flops that constitute the counter are connected serially and the input clock pulse is provided to the first flip flop in the connection. Here the clock input ripples through the counter as the output of the first flip flop generated due to the clock signal is further provided to adjacent flip flop in the forward direction.

Further, in the same way, the present output acts as the clock input for the next and so on. Due to this, in the asynchronous counter, the timing signal gets delayed by some amount on passing through each flip flop. Hence, this results in a propagation delay.

Thus, the above discussion concludes that the synchronous and asynchronous counter possess different characteristics as the clock signal is applied in different ways. Hence these find applications in different fields. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

Skip to content The major classification of counters is synchronous and asynchronous counters. Key Differences Between Synchronous and Asynchronous Counter The synchronous counter is designed in a way where the clock signal acts simultaneously on each flip-flop.

However, the asynchronous counter does not offer this feature as a clock signal is applied separately to each one at an unspecified time interval. While on other hand Asynchronous Counter is more error prone and produces decoding error in the system. As all flip flops are being coordinating with the clock hence the design and implementation is complex as compared to that of Asynchronous Counter.

On other hand as output of one flip flop performing as input of next flip flop the design and implementation is quite simple in case of Asynchronous counter. Synchronous Counter could be operated in any desired count sequence as it could get manipulated by changing the clock sequence.

On other hand Asynchronous counter could operate only in fixed count sequence i. I am also a technical content writer my hobby is to explore new things and share with the world.
