Question

No of states is equal to 2 to the power n in which counter

Answer 1

The number of flip flops(n) required for a desired MOD number-N is found out using the equation:

2^(n-1)<= N <= 2^n

where n is the number of flip flops required.

Examples:- For N=3, from the above equation, n=2 i.e. 2 flip flops are required for MOD-3 counter. Similarly, for N=10 and N=16, we will get n=4. So,4 flip flops are required for MOD-10 and MOD-16 counters. For MOD-32, we get n=5 i.e 5 flip flops are required.
