For an ‘n’ flip flop counter,
- The total number of states = 2n (0 to 2n – 1)
- The largest number that can be stored in the counter = 2n – 1
To construct any mod counter, the minimum number flip flops required such that: Modulus ≤ 2n
Where n is the number of counters.
For example,
A MOD-5 counter requires:
2n ≥ 5
∴ 3 Flip Flops
Calculation:
Number no. of flip – flops are required to construct a mod-12 counter is obtained as:
2n ≥ 12 i.e. n = 4
