32 means 10000 (5 digits); So 32 mod need 5 FFs.

32 mod means till 5 digit number.
So 5 flip flop is required.
So 5 flip flop is required.

MOD 32 means that counter can justify 32 states.
Now, these 32 states can be represented using 5 bits (2^n = 32 => n = 5).

Mod-32 means divide by 32 counter.
2^n=32. => n=5.
i.e. 5 flip flops.
2^n=32. => n=5.
i.e. 5 flip flops.

N = 2^n, for binary counter.
Taking log where N = No. of state.
N = No. of flip flop.
N is equal to logarithm of N to the base 2.
Hence n = 3.32 logN to the base of 10.
N = 3.32*1.5051 = 4.997.
Thus n = 5 flip flop.

We can count up to 31 in mod 32 so 5 bits are enough to count, because if all 5 bits are 1's its equals to 31. i.e 11111 = 31.

2^n = N.
Where n is no.of flip-flops.
N is no.of states.
Where n is no.of flip-flops.
N is no.of states.

N <= 2^n.
Where N is modulus of counter.
n is no.of flip flops.
So when n=5 condition is satisfied.

GIVEN MOD = 32.
We know for the no of clk pulses = 2^n.
where n = no clk pulses.
2^n = 32.
2^n = 2^5.
n = 5.
We know for the no of clk pulses = 2^n.
where n = no clk pulses.
2^n = 32.
2^n = 2^5.
n = 5.

5 flip flops will be required if we count from 0 to 31 for mod 32 we will need 6 flip flops.
