It seems you lack very basic knowledge that can't be filled with two brief paragraphs in a thread reply. You need to dedicate time and effort. You can start with an easy read at our local e-book: http://www.allaboutcircuits.com/vol_4/index.html. I suggest you pick up from Chapter 7.

If you think you want to learn more, you could always turn to digital design books.
