    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
