WHAT DOES LOCAL OSCILLATOR MEAN IN ENGLISH?

Local oscillator

A local oscillator is an electronic oscillator used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning, produces the sum and difference frequencies of the frequency of the local oscillator and frequency of the input signal of interest. These are the beat frequencies. Normally the beat frequency is associated with the lower sideband, the difference between the two. Local oscillators are used in the superheterodyne receiver, the most common type of radio receiver circuit. They are also used in many other communications circuits such as modems, cable television set top boxes, frequency division multiplexing systems used in telephone trunklines, microwave relay systems, telemetry systems, atomic clocks, radio telescopes, and military electronic countermeasure systems. The performance of a signal processing system depends on the characteristics of the local oscillator. The local oscillator must remain stable in frequency. It must produce enough output power to effectively drive subsequent stages such as mixers or frequency multipliers.

Definition of local oscillator in the English dictionary

The definition of local oscillator in the dictionary is the oscillator in a superheterodyne receiver whose output frequency is mixed with the incoming modulated radio-frequency carrier signal to produce the required intermediate frequency.
