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