A sequential circuit has three flip-flops A, B, C ; one input x_in ; and one output y_out . The state diagram is shown in Fig. P5.19 . The circuit is to be designed by treating the unused states as don’t-care conditions. Analyze the circuit obtained from the design to determine the effect of the unused states. (HDL—see Problem 5.41.)

(a) Use D flip-flops in the design.

(b) Use JK flip-flops in the design.
