ABSTRACT:
The electromagnetic environment is the integral part of the world in whichwe live. Various apparatus such as radio and television broadcast stations,
communication transmitters, and other radar and navigational aids radiate
electromagnetic energy during their normal operation. These are intentional and
unintentional radiations of electromagnetic energy into the environment. Many
appliances, such as automobile ignition systems and industrial control equipment
used in everyday life also emit electromagnetic energy although these emissions
are not an essential part of normal operation. The electromagnetic environment
created by these intentional and unintentional sources, when sufficiently strong,
interferes with the operation of many electrical and electronics equipment and
systems which degrades the performance of the system. Electromagnetic
Interference is nothing but electromagnetic pollution. It is neither seen nor sensed
nor audible and hence it is a salient threat.
