Electromagnetic interference includes electromagnetic pulses, spurious
signals spontaneous changes the propagation medium.1 Electromagnetic interference sources
Sources electromagnetic influences are evident throughout the entire
frequency spectrum, from low frequencies (Hz range) high frequencies
(GHz range).2.6.77: The electrical field
is generated result a
potential difference.2 Definition electromagnetic Interference
Electromagnetic interference considered electromagnetic
phenomena, that can impair the performance component, device or
system.

We differentiate between functional (intentional emission) and non
functional sources (unintentional emission). These electrical
signals are superimposed the desired signal. 3.6.
