electromagnetic interference

[i¦lek·trō·mag′ned·ik ‚in·tər′fir·əns]
Interference, generally at radio frequencies, that is generated inside systems, as contrasted to radio-frequency interference coming from sources outside a system. Abbreviated emi.

electromagnetic interference

In the transmission or reception of communication signals, the interference caused by the radiation of electromagnetic fields.

electromagnetic interference (EMI)

The interference of radio reception by the radiation of electromagnetic energy from a piece of electronic equipment or from conductors carrying highfrequency alternating current.


(ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC.
