4 Minimal Sum of Products Expression Implementation from truth table to sum of products expressions. 1. Use Karnaugh map to simplify function f(a, b, c) ? m(0. 2. 3. 7) + ? d(4, 5). List all possible minimal two-level sum of products expressions. Show the switching functions. No need for the schematic diagranm 2. Use Karnaugh map to simplify function f(a, b, c, d)-m(0,4, 5, 7,8, 10, 13) +2d(9, 14, 15) List all possible minimal two-level sum of products expressions. Show the switching functions. No need for the schematic diagram. 3. Use Karnaugh map to simplify function f(a, b, c, d, e)-2 m(0. 2.5, 8. 13, 14, 16, 18, 19, 22, 24, 27, 29, 31)+ d(6.9.?, 15, 25, 30) Write one minimal two-level sum of products expression. Show the switching func- tions. No need for the schematic diagram
