1. The problem statement, all variables and given/known data Recall that the Boolean addition is defined by the rule x XOR y = xy' OR x'y. Consider the Boolean function in four variables w, x, y, z defined by the formula f = w XOR y XOR xz XOR wxz XOR wyz XOR xyz XOR wxyz. A Karnaugh map method must be used to find all simple boolean expressions. I assume it must first be put into a truth table and then go from there. 2. Relevant equations x XOR y = xy' OR x'y 3. The attempt at a solution I attempted to try something like A = w XOR y B = A XOR xz C = B XOR wxz D = C XOR wyz E = D XOR xyz and F = E XOR wxyz. Then using these values in a truth table although i really have no idea what im doing. Is it possible for someone to just say on the right track or wrong? I have been struggling with this for a long time now I'm getting pretty desperate. Thank you. Edit: I'm not being very clear here, I'm just trying to work out how to convert function into disunjunctive normal form so i can then go from there, but I'm unable to do that. thanks.
