1. Show how you can implement the following function using half adder circuits: F(A,B,C) = A BOC 2. Simplify F(A,B,C,D) = AD using KMap, if BCD,BCD, ABCD and ABCD are considered don't care terms. 3. 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 = Ax KA = BJB = Ax KB = A' Find Alt + 1) and B(t+1) and draw the Finite State Diagram. 4.
