$$ P.6 A sequential circuit has two $J K$ flip-flops $A$ and $\underline {B}$, two inputs $X$ and $y$, and one output $z$. The flip-flop input equations and circuit output equation are: \begin{array}{11} \mathbf{J}_{\mathbf {A}}=\underline{\mathbf{B x}}+\mathbf {B}^{\prime] \mathbf {y}^{\prime) & \mathbf {K}_{\mathbf{A}}=\mathbf{B}^{\prime} \mathbf {X y}^{\prime} \mathbf {J}_{\mathbf {B} }=\mathbf {A}^{\prime} \mathbf {x} & \mathbf {K}_{\mathrm{B} }=\mathbf {A}+\mathbf {x y}^{\prime} W \mathbf {z}=\mathbf {A x}^{\prime} \mathbf {y}^{\prime}+\mathbf {B x}^{\prime) \mathbf {y}^{\prime} & \end{array} $$ (a) Draw the logic diagram of the circuit. (b) Tabulate the state table. CS.JG.036
