What's the Local Oscillator

The local oscillator frequency is a term often mentioned in the superheterodyne receivers. The local oscillator frequency is generated by the local oscillator circuit. There is a local oscillator in the superheterodyne receiver, which can output a stable high-frequency electromagnetic wave, which is mixed with the received high-frequency signal to produce a different frequency. This difference frequency is Intermediate frequency, that is heterodyne, which in turn forms superheterodyne receiver.  ...
