Hi. Who among you know a site where I can find a wiring diagram or schematic diagram of PAM (Pulse Amplitude Modulation)? I badly needed a diagram of it for my prototype in Digital Communications. I've been searching for it in Google but it only gave me different diagrams and I can't tell which is which because I've never seen any PAM schematic diagram before. :( The professor only told us that our second prototype is PAM. He only gave a brief description about what a PAM does. If I have not searched in the internet, I won't know that the meaning of PAM is Pulse Amplitude Modulation. An article about what a PAM is, can be found in http://www.tech-faq.com/pulse-amplitude-modulation.html" [Broken] I hope you can help me. Thanks!
