What is Counter ?
The Counter is sequential circuit which counts the number of times the specific event has been occurred. The input to the counter is applied in the form of digital input pulses. The counter counts the high to low or low to high transition of the input pulses and accordingly it increments its count.
Internally, it is the interconnection of the Flip-Flops.

Modulus of the Counter:
The number of different output states through which counter goes before returning back to its first state is known as the modulus of the counter.
For N-bit Counter, the maximum possible value of the modulus is 2^N - 1.
The modulus of the counter can be less than the maximum possible value.
E.g BCD counter is MOD-10 Counter. (Although it is 4-bit counter)

Types of Counter:
1. Asynchronous Counter
2. Synchronous Counter

Applications of Counter:
1. Counting
2. Time Measurement
3. Frequency Division
4. Analog to Digital Converters
