Introduction
The development of electronic equipment has come a long way since the invention of valves and transistors, to the extent that modern society is highly dependent on the smooth functioning of the myriad systems that myriad systems now in operation. Concurrently with that development, Electromagnetic Interference (EMI) has also increased, both in the number of daily incidents and in the severity of the possible consequences. Initially, most of the effects were annoying; for example, crackles on the radio due to a nearby thunderstorm were something one learned to accept. Latterly, some of the effects could be life threatening. The phenomenon described as 'sudden unintended acceleration' could be a case in point. A succinct definition of Electromagnetic Compatibility (EMC) is 'the ability of a device, unit of equipment, or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment'.
