Definition, Meaning & Synonyms
local-oscillator
noun
/ˈloʊ.kəl ˈɒs.ɪ.leɪ.tər/

Definition
A local oscillator is an electronic component that generates a repetitive signal at a specific frequency, used primarily in radio and telecommunications systems.

Examples
- The local-oscillator frequency must match the desired intermediate frequency for accurate signal processing.
- In many radar applications, the local-oscillator signal determines the system’s sensitivity.
- Engineers often test local oscillators to ensure they are functioning within the specified frequency range.

Meaning
In signal processing, a local oscillator helps mix signals for frequency modulation, enabling the reception and transmission of radio waves.

Synonyms
- oscillator
- signal generator
- frequency generator
