A sequential circuit with one input (x) and one output (z) is specified by the following state- transition and output equations: Alt + 1) = x'(A+B) + x B(t + 1) = x'B + XA z = x B (a) Draw the state diagram. (b) Using D flip-flops, draw the logic diagram of the circuit. (c) Using JK flip-flops, draw the logic diagram of the circuit
