Understanding Flip-Flop Truth & Excitation Tables

[ranju]

I am not getting these truth table & excitation table for a flip-flop.. I mean I can understand it but what is the difference between the two?? they are same to a large extent what actually is differentiating an excitation table from a truth table??

Truth Table tells you all the possible combinations of inputs and outputs.

Whereas, an excitation table tells you the inputs required to be applied to the flip-flop to take it from the present state to the next state.
Alternatively, an excitation table tells you the inputs you require for transitions from like 0 (present state) to 1 (next state).
