Design a sequential circuit with two JK flip-flops A and B and two inputs x and y. If x = 1 the circuit remains in the same state regardless of the value of y. When x = 0 and y = 1, the circuit goes through the state transitions from 00 to 01 to 10 to 11 and back to 00 and repeat. When x = 0 and y = 0, the circuit goes through the state transitions from 00 to 11 to 10 to 01 back to 00, and repeat.
