Design a sequential circuit with two JK flip-flops, 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 = 1and x = 1, the circuit goes through the transactions from 00 to 01 to10 to 11 back to 00, and repeats. When E = 1 and x = 0 the circuit goes through the transactions from 00 to 11 to 10 to 01 back to 00, and repeats.
