Lesson description:
The technique for representing information on an ordinary local loop is called analog. This term is often thrown about with little regard for its actual meaning, so we will spend a bit of time understanding what is meant by "analog".
In this lesson, we will understand the term analog, how this relates to copper wires, electricity, circuits and sound.
