Definitions Edit

Radio frequency interference (RFI) is

a disturbance that affects an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from an external source.
[e]lectromagnetic radiation which is emitted by electrical circuits carrying rapidly changing signals, as a by-product of their normal operation and which causes unwanted signals (interference or noise) to be induced in other circuits.[1]

Overview Edit

The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit. The source may be any object, artificial or natural, that carries rapidly changing electrical currents, such as an electrical circuit, the sun or the Northern Lights.
