ABSTRACT
In this chapter, we first introduce analog communication, which has been almost forgotten by both academics and industry experts for many years because of the dominance of digital communication. But our recent research discovers that simulating the behavior of analog communication in digital video communication can provide many interesting features that do not exist in digital communication. This is the reason why we discuss analog transmission technologies here. We also discuss digital communication in the physical layer (PHY), which consists of channel coding and modulation.
