How to convert one flip flop to another

Question

For example,

How do we convert a JK flip flop into a D flip flop? What do we consider in the truth table in the process of doing that?

Thanks

Answer 1

Tie the J input to the D signal, while the K input to the D (D complement), and then the JK flip flop behaves as a D flip flop. Compare the 2 truth tables for the 2 flip flops, and confirm that the same transition Q_n → Q_n+1 takes place for the same input D value.
