oscillator frequency meaning
The fundamental frequency at which an oscillator operates. It can be determined by a tuned circuit, crystal, cavity, section of waveguide or transmission line, or by a resistance-capacitance circuit.

- The local oscillator frequency determines what block of incoming frequencies is downconverted to the frequencies expected by the receiver.
- There are two choices for the local oscillator frequency because the dominant mixer products are at " f"
- He invented a quartz-crystal oscillator frequency standard in 1930, and patented a temperature control oven for crystal oscillators.
- The local oscillator frequency is switched in response to a 22 kHz signal superimposed on the supply voltage from the connected receiver.
- Most receivers are actually superheterodyne receivers and they leak a little of their local oscillator frequency; this can be easily detected.
