I need help, but it is not homework for school. It is homework for myself.
What I am doing now is making a hardwired ROM out of discrete logic gates, and part of my problem is that I am lacking enough knowledge of demorgans theorem.
I know the basics, but when I came to this site:
http://www.generalnumbers.com/demorgans_application1.html
It confused me a bit. It states that
AB + CD = ((AB)' (CD)')'
Now It is easy to prove it by drawing the logic gates out on paper.
But there has to be a way to prove it equation wise.
If so, can someone explain it to me without skipping a step?
