Hi,
So I have a truth table with a function x and all combinations not in the truth table is don't care and i should minimize the function x.
abefg x
11110 0
01000 0
11101 0
11001 0
01011 1
10011 1
10111 1
11000 1
11111 0
11011 0
(If my description is unclear please look at the pdf where i scanned the task)
I do a 5 variable karnuagh map that have this variables as columns and rows then i fill in the karnaugh map, you can se my rows and columns below:
g = 0 g = 1
ab\ef ab\ef
After i fill in the map and group them i get x = b' + a'g + ae'g'
In the solution they do the 5 variable karnuagh map like this:
a = 0 a = 1
be\fg be\fg
They get x = b' + af'g' + a'f
Even if i have different columns and rows should I not get the same answer?
My question is is there a specific rule for what the columns and the rows should be? Why do they take out a?
In the 4 variable kmaps its often a natural rows and columns like ab cd.
Thanks for all help!
