Noise immunity requirements
Electromagnetic compatibility
Electromagnetic Compatibility (EMC) is the ability of an electrical device to operate as
intended in an electromagnetic environment and to operate without emitting levels of
electromagnetic interference (EMI) that may disturb other electrical devices in the vicinity.
