Which Flip Flop is true????????

[life24]

Hi,
Which Flip-Flop always next state independent current state?"
1)D
2)T
3)SR
4)JK

 

[gstekboy]

none of these.

none of these.

But this is multiple question(Test) and i force choice one it.

Draw a table of possible states and input signals and you'll know the answer.

I presume the question refers to state before and after a clock edge and doesn't consider asynchronous inputs.

I think current option is 1(D flip flop.)

I think current option is 1(D flip flop.)

Yes, because a 0 or 1 level at input D forces a respective next output state, independent of present state.

Thanks , But they want next state independent current state

 

[FvM]

Yes, that's case.
