In J-K flip-flop output is fed back to the input. Therefore the change in the output results in changes in the input. Due to this in the positive half of the clock pulse if both J and K are high then output toggle continuously. This is called race around condition.

J-K FF will toggle means it has to behave like a T-FF.
So if we design a T-FF from a J-K FF simply make J=K connection.
Now this FF will behave like T-FF.
When T=1(indirectly J=K=1) in T-FF, it toggeles its input.

Toggle means the output is not fixed. First Q is high next complement of Q becomes high. So output always changes from Q HIGH to complement Q HIGH.

When j=k=1 then the race condition is occurs that means both output wants to become high. Hence there is toggle condition is occurs.

When j=1 and k=1, with each passing clock pulse the output Q changes from 0 to 1 and 1 to 0. That's why its called a toggle state.

Since in SR flip flop S=R=1 Occur Racearound Condition.
So we need for JK flip flop this Toggle J=K=1
So we need for JK flip flop this Toggle J=K=1

When J=K=1, it is possible to set or reset the flip-flop,i.e, TOGGLE occurs

I agree with kalpesh. Toggle condition refers to J=K=1.

Yes @Sonu is write when j=k=1.
That is toggle mode.
That is toggle mode.
