How is Data Sent? An Overview of Digital Communications

Explains how Digital Communications works to turn data (ones and zeros) into a signal that can be sent over a communications channel. Gives basic examples for optical fibres, wireless and mobile communications, as well as an example of data compression and error control coding. Note that there is a minor "typo" near the end, where I wrote "19 bits" when it should have been "18 bits". I've fixed it on the summary sheet: https://drive.google.com/file/d/1q9FN...
