Is there any difference between a heterodyne receiver and a superheterodyne receiver?
- mannykannot 7y ago"Superheterodyne" is a contraction of "supersonic heterodyne", where "supersonic" indicates frequencies above the range of human hearing. https://en.wikipedia.org/wiki/Superheterodyne_receiver https://en.wikipedia.org/wiki/Superheterodyne_receiver
- jhallenworld 7y agoThe super means above hearing range. In a heterodyne receiver (if there was ever such a thing), you would hear the IF frequencies.
- rhinoceraptor 7y agoHeterodyne is a signal processing technique, and superheterodyne is an application of that for radio tuning. This video is a great explainer (and I also highly recommend every other video on the channel): https://www.youtube.com/watch?v=hz_mMLhUinw https://www.youtube.com/watch?v=hz_mMLhUinw
