In a superheterodyne radio, a local oscillator is an electronic circuit that generates a frequency based on the desired channel. The output of the oscillator is the channel frequency typically ...

This allows the local oscillator on the LNB to be referenced to an external signal generator; when fed with a 25.78 MHz signal, it’s enough to goose the LNB up to 10,490 MHz — right about the ...

Later, a number of wireless technologies have emerged, not strictly belonging to the class of communication systems. Some examples are wireless local-area networks (WLAN), sensor networks, wireless ...
