Example Radiating Devices
A computer is a typical example, where spurious emissions may not be contained within the case.
A radio receivers will often 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.
Other examples include the motor, transformer, dimmer, and corona from electrical powerlines. Unintentional radiation from these devices can create interference on AM radio, and on the video of television stations.

Famous quotes containing the words radiating and/or devices:
“The pleasure of eloquence is in greatest part owing often to the stimulus of the occasion which produces it,—to the magic of sympathy, which exalts the feeling of each by radiating on him the feeling of all.”
—Ralph Waldo Emerson (1803–1882)
“Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.... Tooting, howling, screeching, booming, crashing, whistling, grinding, and trilling bolster his ego. His anxiety subsides. His inhuman void spreads monstrously like a gray vegetation.”
—Jean Arp (1887–1948)
