Counter is a register which counts the sequence in binary form.
The state of counter changes with application of clock pulse.
The counter is binary or non-binary.
The total no. of states in counter is called as modulus.
If counter is modulus-n, then it has n different states.
State diagram of counter is a pictorial representation of counter states directed by
arrows in graph.
The clock input is applied.
Count enable = 1.
Counter counts from 0000 to 1111.

4-bit Binary Ripple Counter
All Flip-Flops are in toggle mode. The clock input is applied.
Count enable = 1.
Counter counts from 0000 to 1111.
Synchronous Binary Counter
The clock input is common to all Flip-Flops.
The T input is function of the output of previous flip-flop.
Extra combination circuit is required for flip-flop input.
