This is my K-map
AB 00 01 11 10
CD
00 0 1 x 1
01 x 1 0 0
11 x x x 0
10 0 1 1 1
I found f = AD'+A'B
and from the k-map I found f' = AD+A'B'
But from De Morgan's theorem, if I find the complement of f
f' = AD+A'B'+B'D -> I believe this is still correct according to the K-map, but B'D term is redundant, and have no idea how to simplify.
Many thanks
