Q 10: Obtain the equation for Q in disjunctive normal form (a function of Q. 0 Q Q) Q 11: Simplify the equation using the KV map or Boolean algebra. Make sure that Q or Q." occurs in every term of the equation, so that you can later compare coefficients with the characteristic equation of the JK-FF. Q 12: Obtain Ja und Ka(Jund K of the 4 flip-flop) by comparing cocfficients. The circuit for the counter is shown in Figure 14. However, the logic gates leading to J and K of the 4 flip-flop are missing. Q 13: Draw the gates needed for the 4" flip-flop into Figure 14. Use your results for Ja and Ka from Q12.
