ABSTRACT
It is an unfortunate fact of life that the operation
of virtually all items of electrical and electronic
equipment can potentially disturb the operation of
other nearby items of electronic equipment. In
recent years increasing incidence of interference
has prompted the introduction of legislation that
sets strict standards for the design of electrical
and electronic equipment. The name given to this
type of disturbance is Electromagnetic
Interference (EMI) and the property of an
electrical or electronic product (in terms of its
immunity to the effects of EMI generated by
other equipment and its susceptibility to the
generation and radiation of its own EMI) is
known as Electromagnetic Compatibility (EMC).
EMI (and the need for strict EMC control) can
