1 Electromagnetic interference sources
Sources electromagnetic influences are evident throughout the entire
frequency spectrum, from low frequencies (Hz range) high frequencies
(GHz range).
Electromagnetic interference consists electrical field component and
a magnetic field component H.

signals are superimposed the desired signal. 3.

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

Electromagnetic interference includes electromagnetic pulses, spurious
signals spontaneous changes the propagation medium.
