Radio Technology
In radio technology, the distinction is not the source of the local oscillator, but the frequency used. In heterodyne detection, the local oscillator is frequency-shifted, while in homodyne detection it has the same frequency as the radiation to be detected. See direct conversion receiver.

Famous quotes containing the words radio and/or technology:
“Local television shows do not, in general, supply make-up artists. The exception to this is Los Angeles, an unusually generous city in this regard, since they also provide this service for radio appearances.”
—Fran Lebowitz (b. 1950)
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody elses sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they dont hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
