Design a sequential circuit with two D flip-flops and one input X . When , the state of the circuit remains the same.

Design a sequential circuit with two D flip-flops and one input X . When ± ² , the state of the circuit remains the same. When ± ³ , the circuit goes through the state transitions from 00 to 10 to 11 to 01, back to 00, and then repeats. Draw the logic diagram for the circuit.
