通信网络

前言

Template:Reading level Template:Corequisite

The purpose of this open book project is to provide a free text book about electrical (digital or analog) communication networks. It will be an accompaniment to the Communication Systems book, but will focus more on real-world implementation and less on mathematical theory. See the introduction section for more details.

This book needs help. This is a wiki, so you can help edit it.
