Hi, I'm trying to figure out a few questions on a practice exam that I'm working on for my Intro to Logic Systems class and could use some help. One of the questions (and the others are similar) says: Determine the minimized realization in the sum-of-produicts form using literals of the function: f(A,B,C) = [itex]\Sigma[/itex]m(4,6) + [itex]\Sigma[/itex]d(2,3,7) The given answer is f(A,B,C) = AC'. I know that [itex]\Sigma[/itex]m(4,6) can be represented by AB'C' + ABC' and that [itex]\Sigma[/itex]d(2,3,7) can be represented by A'BC' + A'BC + ABC, but beyond that I am not sure what to do. I think that I need to construct a Karnaugh map from the expression, but am not sure how to do it. Any help is greatly appreciated. Thanks!
