1. Show how you can implement the following function using half adder circuits: F(A,B,C) - ABC 2. Simplify F(A,B,C,D) = ABCD using KMap, if ABCD, BCD and BCD 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 = x KA = B JB = x Kg = A' Find Alt + 1) and B(t+1) and draw the Finite State Diagram. 4. Find VR3 using superposition theorem: RS VR3 w w R 40 20 602 1 4A E = 12V 20 V 5. Find Thevenin's and Norton's equivalent circuits seen between terminals a and b: 3A 622 1 412 8A w 8 20 V
