Question about K-map

  1. Sep 7, 2009 #1
    1. The problem statement, all variables and given/known data
    I understand the basic of kmaps like
    xy+xy' =
    y y'
    x 1 1
    x' 0 0

    would be x.

    but when we have (x+y)(x+y'), how would that be setup?

    The easiest way is change the product of sums to a sum of products by "multiplying it out" using the properties of and, or, and complement and simplifying. Alternatively you can evaluate the expression for the four possibilities (x,y) = (0,0) or (0,1) or (1,0) or (1,1) in fill in the K- table with the results.
