a. Draw the state diagram given this state/output table. Use the same state labels as in the table.
b. Write at least 1 complete sentence describing the function of this circuit based on your state diagram.
c. Based on Table 1, finish the design of the sequential circuit. Use two D flip-flops with state variables ????2????1 and state assignments ???? = 00, ???? = 01, ???? = 11, and ???? = 10. Derive the excitation equations for ????2 and ????1 and the output equation for ????, and draw the circuit.
