Question

How many flip‐flop will be complemented in a 10‐bit binary ripple counter to reach the
next count after the following counts?
(a) *1001100111

Comments

is it 4 ?

ya how?

Answer 1

If I'm right then they are asking about Binary Up Counter (basic counting of asynchronous counter)

So in the next Step it will increment by 1: i,e 1001100111 -> 1001101000 ;  (615 -> 616)

Previously all the counter have the value as 615 i,e; 1001100111

Next step all will become as : 1001101000

So, last four bits complemented i,e 4 FFs will complement their value

Answer should be 4

Comments

everything is k accept 4 counters will complement their value

not get yr

clarify it.

My mistake, its FFs not counters

FF stores 1 bit. All 10 FFs have value 1001100111 respectively,

But after increment they have 1001101000 resepectively.

So by looking at values- only 4 FFs have changed their value either from 1->0 or 0->1. (i,e complemented)

So 4 FFs.

now it sense

tie.
