2. Simplify F(A,B,C,D) = ABCD using KMap, if ARCD, BCD and ABCD are considered don't care terms. 3. A sequential circuit has two k flip-flops A and B and one input x. The circuit is described by the following flip-flop input equations JA = x K4 = x Je = B kg = A' Find Alt + 1) and B(t+1) and draw the Finite State Diagram
