Explain Counters in Digital Circuit|Type of Counter and its Circuit Diagram

By on 02:17

Counter:-Counter is a circuit(sequential) which count the sequence of digital input pulse or in simple words Counter is an device which is used for counting number of clock-pulse that's why we called this term as counter.Counters is divided into many type namely Synchronous Counter,asynchronous counter or Ripple Counter,mod-n counter(Single mode,multi-mode),Ring Counter etc but its 2 main categories are Synchronous Counter and asynchronous counter.Counter is also used for measuring frequencies.

1)Asynchronous Counter or Ripple Counter:-In this counter each Flip Flop is triggered by the output of previous Flip Flop.

Now I explain it with an example of 4 bit Asynchronous Counter:-

Example of 3 bit Asynchronous Counter:-

2)Synchronous Counter:-Synchronous Counter is most simplest form of counter because it required less no. of hardware but speed of operation is very slow.

If you have any query then leave your comments and don't forgot to follow me on Google+,Facebook,Twitter. 


  1. hi..

    i am priya doing in vlsi.
    i need some more details about the types of counters with its graph explanation.
    can u help me/

  2. Hello Priya,Counter is generally divided into 2 parts i.e.Synchronous and Unsynchronous but apart from that counter has many other type like Ring Counter,Decade Counter,up/down counter,Johnson counter etc and for graph representation than you have to give me your gmail(or email) id then I will send .pdf file to your inbox....thanks

  3. Hello
    my name is jay .i am btech student .my guiry is what is single mode and multimode counter.

  4. Hi,
    Nice Information
