The problems with S-R flip flops using NOR and NAND gate is the invalid state. This problem can be overcome by using a bistable SR flip-flop that can change outputs when certain invalid states are met, regardless of the condition of either the Set or the Reset inputs. For this, a clo...
JK Flip Flop to SR Flip Flop 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 ...
For understanding the working of SR NOR latch, we need to have a look at the truth table of the NOR gate (given below) which showsif any of the input is 'high' output becomes 'low', irrespective of the other input. Case 1: When R=0 and S=0 Let us suppose, initially the value ...
