Poll of the Day > Do my own damn homework (Digital Logic)

(+) Yeah! (+)

I have (w' +x) (y+ z) (w' + y) (x + y' + z). I need to convert it to a Sum of Product.

I made a Truth Table which is the following:

w|x|y|z|f
0|0|0|0|0
0|0|0|1|1 w'x'y'z
0|0|1|0|0
0|0|1|1|1 w'x'yz
0|1|0|0|0
0|1|0|1|1 w'xy'z
0|1|1|0|1 w'xyz'
0|1|1|1|1 w'xyz
1|0|0|0|0
1|0|0|1|0
1|0|1|0|0
1|0|1|1|0
1|1|0|0|0
1|1|0|1|1 wxy'z
1|1|1|0|1 wxyz'
1|1|1|1|1 wxyz


I have no idea if I did that truth table correctly. I could also solve it algebraicly, but I ended up with a mess that is [x(y'+z)+w'](y+z), when that is also wrong. The final answer is xy+w'z, but the professor doesn't care about the answer, but instead wants us to show the work instead.

So, what am I missing here?

Didja shove it in a k-map to simplify the truth table?

Nope.

We just started K-maps yesterday, long after this assignment was given.
