EMC Definition
Definition
The capability of electrical devices and systems to operate
in their electromagnetic environment without disturbing or
being disturbed by them.
EMC = EMI + EMS
EMI (Interference / Emission)
Radiated EMI, e.g. CISPR 22
Conducted EMI, e.g. CISPR 14
EMS (Susceptibility / Immunity)
Radiated EMS, e.g. EN61000-4-3
Conducted EMS, e.g. EN61000-4-6
