A number of specialized terms are applicable to the characterization, specification, and/or measurement of electromagnetic interference (EMI). It is particularly important that individuals responsible for ensuring that equipments and/or systems operate in an electromagnetically compatible manner be familiar with the basic terms and definitions that are widely used throughout the electromagnetic compatibility (EMC) community. This chapter presents a discussion of the basic terms and definitions that are important to the EMC engineer or technician.
