In this case we are required to convert SR flip flop into JK flip flop. Therefore we have to first design and connect the combinational circuit to the input of SR flip flop so that it will produce same outputs as that of JK flip flop. Here the external inputs are J and K. S and R will be the outputs of designed combinational circuit which are inputs of actual flip flop. We write a truth table with J, K, Qn, Qn+1, S and R. where Qn is the present state of the flip flop and Qn+1 will be the next state obtained when the particular J and K inputs are applied.

J, K and Qn can have eight combinations. For each combination of J, K and Qn find the corresponding Qn+1, i.e. determine to which next state the JK flip flop will go from the present state Qn if the present inputs J and K are applied. Now complete the table by writing the values of S and R required to get each Qn+1 from the corresponding Qn. i.e. write what values of S and R are required to change the state of the flip flop from Qn to Qn+1.
