sentences:  In order to obtain the excitation table of a flip-flop, one needs to draw the Q(t) and Q(t + 1) for all possible cases (e.g., 00, 01, 10, and 11), and then make the value of flip-flop such that on giving this value, one shall receive the input as Q(t + 1) as desired.The characteristic equation of a T flip-flop is formula_1.The characteristic equation of a SR flip-flop is formula_2.
