3. a) Map the following function on a Kmap: f(A, B, CD) = Em(0,2,4,5,10,12,15) + Zd(8,14) b) Circle all of the prime impiicants in the Kmap. Place an asterisk (*) next to the '1's in the K-map that make them essential. List all of the essential prime implicants of the function in the space below. c) find all minimum sum of products expressions (2 solutions). 4. For each of the following, i. List all prime implicants, indicating which are essential. ii. Find minimum sum of products expression. a. hm, b, c) = Em(0, 1, 2, 5, 6, 7) b. g(w, x, y, z) = Zm(0,3,4,5,8,11,12,13,14,15) 5. Obtain minimum POS (product of sum) expression for the following function using Kmaps u, b, c, d) = Zm(O, 2, 4, 6, 7, 9, 11, 12, 13, 14, 15)
