1. Show how you can implement the following function using half adder circuits: F(A,B,C) = BC + ABC 2. Simplify F(A,B,C,D) CD using KMap, if BCD, ABCD, 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= B KA = x JB = A Kg = A' Find Alt + 1) and B(t + 1) and draw the Finite State Diagram. 4. Find I, using superposition theorem: 1 6A RX1401 JA R240 RS 5. Find Thevenin's and Norton's equivalent circuits seen between terminals a and b: w 4 6V S = x'y + xy' C = xy
