Toggles means what?
Sudhaa said:   1 decade ago
Changing from one state to other.
Teja said:   1 decade ago
I hope the output toggles when the state changes from to 1 to 0.

But I can't get the question?

@Varsha.

Toggle means all input state 11.
Varsha singh said:   8 years ago
If counter is made up of JK FF then for input 11 output will Toggle (change from 0 to 1 or vice versa).

Why not B? I think option B is also right.
Dhanya said:   7 years ago
Both option A and B are correct I think.

Actually the o/p of FF in ripple counter is toggles when there is a transition of either 0 to 1 or 1 to 0, depending on the clock is positive edge or negative edge triggered.
