We can't _hear_ the Signal without the devices, and if we try we get a shocking experience. We talk into a device & listen to a device - that's the Data. There's a lot of physics in the process and I'll try to cover what's necessary for understanding what's needed in later courses.Ī telephone conversation provides the clearest example of Analog Data carried on an Analog Signal. Transmitting them via an appropriate facility, and making conversions as needed on the receiving end.

This Chapter focuses on these concepts and examines processes involved in taking analog or digital data, converting them to either analog or digital signals, The last chapter discussed Essential Concepts, including Analog & Digital Data & Signals. INFO370 - Analog & Digital Communications Concepts
