In my earlier post I discussed on conversion of D Flip flop to SR Flip flop. Now we see conversion of D Flip flop to JK Flip flop by some simple steps.
Step 1 : For conversion of D Flip flop to JK Flip flop at first we have to make combine truth table for JK flip flop and D Flip Flop. In bellow see the combine truth table of JK flip flop and D Flip Flop.
From above truth table we can understand that what are those different inputs of D flip flop and JK flip flop, we need to get the output Q.
Step 2 : Now from above truth table we can draw the Karnaugh map for input of JK flip flop. Then we can easily get the relation between JK with D. For that see bellow
Now from this above Karnaugh map we get the relation D = JQ^ + K^Q.
Step 3 : Now as per the relation of J K with D flip flop from Karnaugh map we can easily build JK Flip Flop using D Flip Flop.
