42.1 Introduction

The term “electromagnetic interference” (EMI) refers to the disturbance of operation of an engineering system due to an electromagnetic impact of the same system or other systems. Conducted electric noise and radiated electromagnetic noise are typical culprits. Watching TV in industrial centers of Western Europe in late 1960s was virtually impossible during work ...
