Why electromagnetic compatibility (EMC)?

Modern society would be very different without the proliferation of electronic systems such as communication, navigation, and consumer electronics systems; electromagnetic interference (EMI) is the byproduct of these electronics systems. For modern society to use all its electronic systems effectively, EMI should be contained and electromagnetic compatibility (EMC) must be enhanced. This paper introduces the concepts of EMI and EMC for a practising engineer. It emphasizes the need for EMC during the product design phase by providing numerous case history examples.
