Q. Find the minimum SOP and POS expression for the following functions using K- Map and realize the expression using appropriate gates. Also realize SOP form using NAND-to-NAND gate network and convert this gate network to a AND-to-OR gate network. Use as few gates as possible.
1. F(A,B,C,D) = ∑m (0,1,2,7,8,10,13,15) + ∑d (9,14)
2. F(A,B,C,D) = ∑m (0,1,2,3,7,8,10) + ∑d (5,6,11,15)
