Dispersion of electromagnetic interference
In a system or installation electromagnetic interference can only occur
if the following components are mutually present:
if the following components are mutually present:
Source of interference
Interference path
Susceptible equipment.
If one of these components is not present (for example the
interference path), no interference will occur even if the source of
interference sends high levels of interference (Fig. 1):
