MadeEasy Test Series 2018: Digital Logic - Digital Counter

Question

A binary ripple counter is created by cascading N-number of flip-flops. The output frequency of every flip flop is named after its position i.e. then the MOD of the counter is ________.

(Assume N > 6)

A.) 8

B.) 11

C.) 14

D.) None of these

Comments

@saxena0612 you got N=11

that is no. of flip flops

each flip flop is a MOD 2 counter

so N flip flops will act as

2*2*2*........(N times) = 2^N

please tell me where i am wrong

@ashish pal

your reasoning and your answer are exacly correct.

@Avdesh Singh Rana

2048 are no of states which can generate by the counter.

Mod 11 is correct

the no. of distinct state generated by the counter is known as its mod, therefore it is $mod2^{11}$ counter

Yes ! I was holding the total no of flipflops but here mod is asked .States will be $2^{11}$ and mod will be 2048 Thanks nitish.
