3.15 Simplify the following Boolean function F, together with the don't-care conditions d, and then express the simplified function in sum-of-minterms form: (a) F(x, y, z) = (0, 1, 4, 5, 6) d(x, y, z) =Σ(2, 3, 7) (b) F (A, B, C, D) = d(A, B, C, D) = (c) F (A, B, C, D) = (d) F (A, B, C, D) = Σ(0, 6, 8, 13, 14) Σ(2, 4, 10) Σ(5, 6, 7, 12, 14, 15,) Σ(4, 12, 7, 2, 10,) d(A, B, C, D) =Σ(3, 9, 11, 15) d(A, B, C, D) = Σ(0, 6, 8)
