For the following Boolean function expressed in the canonical SOP form, answer the following: F(A, B, C, D) = ∑m(4) + ∑d(5, 6, 7, 8, 9, 10, 11, 12, 13, 14) where m represents minterms and d represents don't cares. 1. List all prime implicants of F. 2. List all essential prime implicants of F. 3. Simplify F into a minimal sum-of-products expression. 4. Simplify F into a minimal product-of-sums expression. 5. The total number of gates used in the AND-OR implementation of F is _____ and the number of gates used in the OR-AND implementation of F is _____
