Homework Help: K-Map w/Don't Cares

  1. Apr 14, 2013 #1
    I am trying to find the minimum AND-OR expression in a K-map with Don't Cares. My Karnaugh map is attached below.

    Here is the min AND-OR expression, I believe.

    b'd' + b'c + ac

    For a little more clarity: E(0,3,14) + d(2,4,7,8,10,11,13,15)

    Since you didn't show your variables a,b,c,d on the K map, it's hard to verify your expression, although I do get a similar form with 3 groups on the K map each including 4 squares.
