Editing Unintentional radiator (section)

==Example unintentional and incidental radiating devices==
A [[computer]] is a typical example of an unintentional radiator. Radio frequency signals used within the computer circuitry may be unintentionally coupled to the power cord or to an interconnecting cable, which then acts as an antenna.

A [[receiver (radio)|radio receiver]] will often use an [[intermediate frequency]] which is detectable outside the radio&mdash;the concept behind at least one [[audience measurement]] concept for roadside detection of [[radio station]]s which passing [[motorist]]s are listening to.

Examples of incidental radiators include [[electric motor|electric motors]], [[transformer|transformers]], [[dimmer|dimmers]], and [[corona discharge|corona]] from [[electric power transmission|electrical powerlines]].  Radiated emissions from these commonly create [[Interference (communication)|interference]] on [[AM radio|AM radio receivers]] and on [[television]] receivers.
