On that receiver, the two signals mixed just as they did in the original heterodyne concept, producing an output that is the difference in frequency between the two signals. ... In this case, all of the frequencies are well beyond the audible range, and thus "supersonic", giving rise to the name superheterodyne.
Why do we use superheterodyne?
Benefits or advantages of Superheterodyne Receiver
The devices are cheaper at such lower frequencies compare to higher frequencies. ➨It is easy to filter IF signal compare to RF signal. ➨It offers better sensitivity compare to homodyne receiver architecture.
What is meant by superheterodyne receiver?
/ (ˌsuːpəˈhɛtərəˌdaɪn) / noun. a radio receiver that combines two radio-frequency signals by heterodyne action, to produce a signal above the audible frequency limit. This signal is amplified and demodulated to give the desired audio-frequency signalSometimes shortened to: superhet.
