Examples

A local oscillator provides the mixing frequency; it is usually a variable frequency oscillator which is used to tune the receiver to different stations. Source: Internet

A method of significantly reducing the local oscillator radiation from the receiver's antenna is to use an RF amplifier between the receiver's antenna and its mixer stage. Source: Internet

In addition to the magnetron (right), it contains a TR (transmit/receive) switch tube and the superheterodyne receiver front end, a 2K25 reflex klystron tube local oscillator and a 1N21 germanium diode mixer. Source: Internet

In order to tune the receiver to a particular station, the frequency of the local oscillator is controlled by the tuning knob (for instance). Source: Internet

Frequency synthesis In digital wireless communication systems (GSM, CDMA etc.), PLLs are used to provide the local oscillator up-conversion during transmission and down-conversion during reception. Source: Internet

In a 1905 patent, Fessenden stated the frequency stability of his local oscillator was one part per thousand. Source: Internet
