I have an exam tomorrow and I just can't seem to find the information to solve a problem like this

let's say I wanted to convert a D FF to a JK FF (or vice versa).

I'd need a stable table diagram. For this example I'd use J and K and Present state. But what would be the process of completing this table..

an SR example would help to since D is probably one of the easier FF's. Thanks for the assistance anyone..

J K Q0 Q1 D
0 0 0
0 0 1
0 1 0
0 1 1
1 0 0
1 0 1
1 1 0
1 1 1

The truth table for a D-FF is
D Q0 Q1
0 . x . 0
1 . x . 1

so find a situation on the JK-FF such that if j = n and k = m, Q1 will always be 0 regardless of Q0.

then find the same thing so Q1 is alwasy 1 regardless of Q0
