A sequential circuit has two JK flip-flops A and B, two inputs r and y, and one output z. The flip-flop input equations and circuit output equation are
JAJBz=A′x+B′y=A′xy=A′x′+B′y′KA=Bx′y′KB=A′+B′x(a) Derive the simplified state equations for A and B. (b) Tabulate the state table. (c) Draw the state diagram of the çircuit.
