Q2): Design a sequential circuit with two T flip-flops A and B, and one input x_in. (a) When x_in=0, the state of the circuit remains the same. When x_in= 1, the circuit goes through the state transitions from 00 to 01, to 11, to 10, back to 00, and repeats. (b) When x_in=0, the state of the circuit remains the same. When x_in=1, the circuit goes through the state transitions from 00 to 11, to 01, to 10, back to 00, and repeats
