5.9 A sequential circuit has two JK flip-flops A and B and one input x. The circuit is described
by the following flip-flop input equations: JA = x JB = A	KA = B KB = x

(a)* Derive the state equations A(t + 1) and B(t + 1) by substituting the input equations for the J and K variables. (b) Draw the state table and state diagram of the circuit.
