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.

  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
