We differentiate between functional (intentional emission) and non
functional sources (unintentional emission).2.

Electromagnetic interference consists electrical field component and
a magnetic field component H.
Electromagnetic interference includes electromagnetic pulses, spurious
signals spontaneous changes the propagation medium. These electrical
signals are superimposed the desired signal.2 Definition electromagnetic Interference
Electromagnetic interference considered electromagnetic
phenomena, that can impair the performance component, device or
system.Hoods and Housings 55
