Electronic circuits must perform two different functions: (1) they must respond to desired signals, and (2) they must reject undesired signals. But the world is full of a variety of interfering signals, all of which are grouped under the headings electromagnetic interference (EMI) or radio-frequency interference (RFI). These EMI/RFI sources can ruin the performance of, or destroy, otherwise well-functioning electronic circuits. Oddly, most circuits are designed for function 1: they do, in fact, respond properly to desired signals. But many, many devices fail miserably ...
