3. Simply the following Boolean function F, together with the don't-care conditions d, and then express the corresponding simplified function in sum of minterms: (a) F(x,y,z) = (1,4,6) d(x,y,z) = 2 (0,2,7) (b) F(A,B,C,D) = {(1,5,6,7,13) d(A,B,C,D) = 2 (8,4) 4. Simplify the following Boolean functions in product of sums: (a) F(A,B,C,D) = A'B'+CD'+ABC+A'B'CD'+AB'CD (b) F(A,B,C,D) ||(2,3,4,9,11) 5. NAND/NOR implementation: (a) Simplify the following function and implement it with two-level NAND gate circuit: F(A, B, C, D) = A'B'C'D+CD+ AC'D (b) Simplify the following function and implement it with multi-level NOR gate circuit: F(w, x, y, z) = (0,3, 12, 15) 6. Multilevel NAND/NOR implementation: (a) Draw the multiple-level NAND circuit for the following expression: +z) + xyz (b) Draw the multiple level NOR circuit for the following expression: w(x + y
