Unintentional radiator

From Free net encyclopedia

An unintentional radiator is any device which creates radio frequency energy within itself, of which a significant amount does not normally leave the device or its housing, unless it is damaged or malfunctioning.

A computer would be an excellent example, as all spurious emissions should normally be contained within the case. Likewise, radio receivers use an intermediate frequency which is detectable outside the radio—the concept behind at least one audience measurement concept for roadside detection of radio stations which passing motorists are listening to.
