5 Minimal Product of Sums Expression Implementation from truth table to product of sums expressions. 1. Use Karnaugh map to simplify function f(a, b, c) = E m(1,6) + Ed(2,4). List all possible minimal two-level product of sums expressions. Show the switching functions. No need for the schematic diagram. 2. Use Karnaugh map to simplify function f(a, b, c, d) = Em(1, 3, 6, 7, 9, 11) + Ed(8, 12, 14). List all possible minimal two-level product of sums expressions. Show the switching functions. No need for the schematic diagram. 3. Use Karnaugh map to simplify function f (a, b, c, d, e) = m(1, 3, 4, 6, 11, 12, 14, 15, 17, 19, 20, 22, 27, 28, 30)+3d(5, 7, 8, 10, 24). Write one minimal two-level product of sums expression. Show the switching func- tions. No need for the schematic diagram
