Q. Explain working of Counters?
A counter is a register that goes through a predetermined sequence of states when clock pulse is applied. In principle value of counters is increased by 1 module the capacity of register it implies that when value stored in a counter reaches its maximum value next incremented value becomes zero. Counters are mostly used in circuits of digital systems where control and sequence operations are performed for illustration in CPU we have program counter (PC).
Counters can be categorized in two categories based on the manner they operate: Asynchronous and synchronous counters. In Asynchronous counters change in state of one flip-flop triggers other flip-flops. Synchronous counters are relatively faster since state of all flip-flops can be changed at the same time.
