ABSTRACT
In Chapter 8, we discussed analog and digital communication. We treated the basics of analog radio, including the modulation of carrier waves to carry information. We also discussed frequency multiplexing, which allows a single physical medium to carry many communication channels. We discussed digital sampling of an analog signal to change it to a binary form suitable for transmission across a digital communication channel. Digital communication requires use of a chosen protocol-a set of rules for interpreting a list of binary numbers.
