Jump to PostI just wanted to point this out. There is a very important error in the truth table that you posted, it should be this:
A B C D Y 0 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 1 …
Not doing your homework for you, but will give a clue, think bit-wise comparisons based upon some bit of information in your "truth table".

Without that correction, there is no way that this could work. And with the correction, it becomes pretty obvious that only A and B matter, so, concentrate on that.
Yea. I was able to figure out was wrong, noticed the mistake on my lab and we have finally learned kmaps which I have been using.
