In telecommunication, electromagnetic interference control (EMI) is the control of radiated and conducted energy such that emissions that are unnecessary for system, subsystem, or equipment operation are reduced, minimized, or eliminated.
Note: Electromagnetic radiated and conducted emissions are controlled regardless of their origin within the system, subsystem, or equipment. Successful EMI control with effective susceptibility control leads to electromagnetic compatibility.

Electromagneticinterference (EMI) is an electromagnetic or electrostatic disturbance that causes electronic equipment to malfunction or to produce undesirable responses or conditions.
The key to reducing shipboard EMI is to first identify the source of the offending electromagnetic energy, then to determine a method of correction and, finally, to correct or minimize the effect.
Interference that occurs as the result of mixing two signals (heterodyning) in a nonlinear element such as the first stage of a receiver or the final stage of a transmitter.
