2. (20 points) Simplify the following Boolean functions to minimal SOP and POS using K map: a. F(W, X, Y, Z) -11 (1,2,4,8,15), d(W, X, Y, Z) =(5,7,10,12) b. F(W, X, Y, Z) - (0,1,6,15), d(W, X, Y, Z)=(3,5,7,11,14) c. F(A, B, C, D) - (A+B+D') (A' + B'+C')(A' +B'+C)(B'+C+D') d. F(A, B, C, D = A'C+ A'BD'+BC'D+ AB'D+ AB'CD
