What is excitation table? List the excitation table for SR-FF, JK-FF D-FF and T-FF.

Flip-flop specifies the next state when the input and the present state are known. During the design of sequential circuits, the required transition form present state to next state and to find the FF input conditions that will cause the required transition. For this reason we need a table that lists the required input combinations for a given change of state. Such a table is called a flip-flop excitation table.
