Question 3: (12.0 Points; 4,0 + 4.0 + 4.0) Consider the following problem: Four plates of salad w, x, y and z are placed in sequence on table. Each one may be full i.e. 1 or empty i.e. 0. A Boolean function F is l iff there are at most two plates are empty. 1. Give the truth table defining the Boolean function F. 2. Express F as a minimum SOP. 3. Draw the logic diagram. Ans: Truth Table K-Map SOP w x y z F yz WX F = Logic Diagram of SOP
