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
