Find the minimum SOP function (Karnaugh map)

[omni]

first i hope is the correct forum to ask this kind of question.

so i asked to find the minimum SOP function from the Karnaugh map (given in the picture).

so i started to solve it as you can see in the picture.
and this what i got:fsop=AB+BC+ACD'X' till here i think is ok.

now this is all what i tried to do: AB+BC+ACD'X'+A'DY.

hopw you can help me here.


thanks.

What mean the AB, !C+Y, AZ, !AX, !X in map cells?

hey, i just solve it.

i can know the value of A,B,C.

now if i can know what is A,B,C. i get:fsop=BC+AB+ACD'X'+BDX'+A'DY

what i did is first take all the "1" (if i can use with Phi so i also use it).
then i take the Variables (if i can use here with "1" of Phi i use it.)

thank you.
