# If 'N' number of flipflops are utilized, then the output frequency of last flip-flop is equivalent to _____.

## If 'N' number of flipflops are utilized, then the output frequency of last flip-flop is equivalent to _____.

a. 2^{N} of the input frequency

b. 1/ 2^{N} of the input frequency

c. 1-2^{N} of the input frequency

d. 1/ 2^{N-1} of the input frequency

Correct Answer : b. 1/ 2^{N} of the input frequency

**Explanation :**

2^{N} different states of counter are taken into consideration before returning to zero state (MOD Number Representation).
