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.
Calculation:
Number no. of flip – flops are required to construct a mod-200 counter is obtained as:
2n ≥ 200
For n = 8
28 = 256 > 200
∴ 8 flip-flops required to construct a counter to count upto 200 (decimal)
