​​​​Morris Mano Edition 3 Exercise 6 Question 12 (Page No. 254)

Question

 A sequential circuit has two JK flip-flop, A and B, two inputs, x and y; and one output, z; The flip-flop input functions and the circuit output function are as follows:

$JA= bx + b’y’$     $KA= B’xy’$

$JB = A’x$              $KB=A + xy’$

$z = Axy + Bx’y’$

1. draw the logic diagram of the circuit.
2. tabulate the state table.
3. Derive the next-state equations for A and B.
