Argh, I say. Argh.

I have this circuit. I have to simplify this circuit using boolean logic. For about two and a half hours I repeatedly reworked it and got different answers. Then I finally got to the point where reworking it kept getting me the same answer. However, now I keep getting the TRUTH TABLES turning out differently. Basically, I just want to know if I'm on the right track or not.


I get that reducing to a'd + b'd + c + ab . Anyone who knows this stuff and feels like helping, am I right? Or do I need to work it again?

truth table for me came out to be all 1's except for (a = 1 b,c,d = 0) and (b = 1 and a,c,d = 0)

dammit. all 0's is a zero as well.
