I've always been annoyed with the sheer amount of theoretical knowledge about digital communication systems with little or no applications to really sink your teeth into and mess around with. In this project, I hope to provide a simple and cheap way to get your hands dirty with digital communications by building a complete communication system from the ground up using only through-hole components on a breadboard.
While a full understanding of all the intricacies of this project would require an undergraduate electrical engineering degree, I hope that anyone with a basic understanding of digital logic and circuits can follow along. We'll start with the modulation of digital data onto an analog carrier, then devise a way to demodulate the signal on the other side, and finally talk about different channels our system might use to send the data.
As a disclaimer, I would like to say that I don't know everything about this subject. At the time of writing this, I am still a green-gilled electrical engineer and learning as I go, but I think I have a lot to offer on this subject. I will try my best to setup a means for feedback and questions on my website, but if that doesn't pan out emailing me at floratos.engineering@gmail.com should always work.
