3.6.2 Definition electromagnetic Interference
Electromagnetic interference considered electromagnetic
phenomena, that can impair the performance component, device or
system.78: The magnetic field
is generated current
flowing electrical
conductor.2.
We differentiate between functional (intentional emission) and non
functional sources (unintentional emission).
Fig.77: The electrical field
is generated result a
potential difference.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 includes electromagnetic pulses, spurious
signals spontaneous changes the propagation medium.
