We first write the truth table for required Flip-flop i.e. JK FF
Now we write the excitation table of given FF SR flip-flop as
Now we combine two tables to get the combinational circuit as:
Now we design the combinational circuit to convert J, K to corresponding R, S
K-map for S input:
K-map for R input:
So we get the circuit to convert RS FF to JK FF:
