*Electromagnetic Compatibility*. This is a fairly lengthy (200+ pages) document which addresses the concept of dealing with EMI & RFI with a focus on maintaining compatibility among systems which occupy the same spectrum space. It is written at a "technician's level" with minimal emphasis on mathematical equations, numerous diagrams and clear and concise descriptions of problems and their solutions.

One of the concepts presented early on in this document is the concept of harmonics. Here is a simulator that we'll discuss in class which shows the relationship between waveform shape and harmonic content. www.Falstad.com/fourier.

While we don't have time to cover the entire document in class, I encourage you to put this on your "reading list" to read in its entirety.
