# Sr flip flop excitation table

Art terminologyAug 11, 2018 · SR Flip Flop to D Flip Flop As shown in the figure, S and R are the actual inputs of the flip flop and D is the external input of the flip flop. The four combinations, the logic diagram, conversion table, and the K-map for S and R in terms of D and Qp are shown below. This will set the flip flop and hence Q will be 1. On the other hand if Q = 1, the lower NAND gate is enabled and flip flop will be reset and hence Q will be 0.
