How is Data Received? An Overview of Digital Communications

Explains how Digital Communication Receivers work to turn the received waveform back into data (ones and zeros). Discusses the basic fundamental situation for wireless and mobile communications, and for Ethernet, digital subscriber lines (DSL), and optical fibres.

This is Part 2 of an overall system overview. The Transmitter was covered in Part 1 "How is Data Sent? An Overview of Digital Communications" https://youtu.be/MAddbFfCsIo

* Note that I made a minor error in showing the Detector before the Equaliser. What I had intended to do was to show them as a single block, since they are most often implemented as a single function (but I was trying to think of too many things at once). If they are implemented separately, then the equaliser comes first. I have fixed it on the Summary Sheet.
