local oscillator

n
(Electronics) electronics 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
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.local oscillator - an oscillator whose output heterodynes with the incoming radio signal to produce sum and difference tones
heterodyne receiver, superhet, superheterodyne receiver - a radio receiver that combines a locally generated frequency with the carrier frequency to produce a supersonic signal that is demodulated and amplified
oscillator - generator that produces sonic oscillations or alternating current
