The basic definition of EMC is:
The ability of a device or system to function normally in its electromagnetic environment and not to cause unbearable electromagnetic disturbance to anything in the environment. The so-called electromagnetic harassment refers to the equipment or system performance degradation caused by electromagnetic harassment.
It has two meanings:
EMI is a kind of electromagnetic interference.
Refers to the equipment itself in the work of the electromagnetic disturbance to the environment
EMS (Electro Magnetic Susceptibility)
Refers to the equipment has a certain resistance to electromagnetic interference in the electromagnetic environment.
