Question: (a) Draw an SM chart that is equivalent to the state graph of Figure 4-46. (b) If the SM chart is implemented using a PLA

(a) Draw an SM chart that is equivalent to the state graph of Figure 4-46.
(b) If the SM chart is implemented using a PLA and three flip-flops (A, B, C), give the PLA-table (state transition table). Use a straight binary state assignment.
(c) Give the equation for A⁺determined by inspection of the PLA table.
(d) If a one-hot state assignment is used, give the next-state and output equations.
