Voltage-contrôlé oscillateur ka jogo bɛ jira ni curve ye (Ja 1) min bɛ jɛɲɔgɔnya jira bɔli angular frequency ω0 ni donna control voltage uc cɛ. Jaa in na, kɛrɛfɛla ω0,0 ni uc ye zeru ye, o bɛ wele ko hɔrɔnya-boli kɛrɛnkɛrɛn; kurunba in jiginni K0 min bɛ ω0,0 la, o bɛ wele ko kɔrɔsili sɛgɛsɛgɛli. Kumaɲɔgɔnya walima sumanikɛminɛnw na, donna-kɔlɔsili-minɛnw ye taamaʃyɛn ye min ka kan ka Lase walima ka suman (signal modulateur).
Voltage-controlled oscillator bɛ wele tuma caman na ko frequency modulator, min bɛ kɛ ka frequency-modulated signal dilan. Otomatiki frequency control loops ani phase-locked loops kɔnɔ, donna control voltage ye fili signal voltage ye, ani voltage-controlled oscillator ye controlled component ye loop kɔnɔ.
VCO suguyaw ye LC, RC ani kristali ye. Fɛɛrɛko wajibiyalen kunbaba minnu bɛ kɛ ni tension-contrôlés oscillateurs ye, olu ye frequency sabatili ɲuman ye, control sensitivity high, frequency modulation range (fɔkan modulation range) ka bon, jɛɲɔgɔnya linear min bɛ frequency deviation ni control voltage cɛ, ani integration nɔgɔya. Kristali voltage-contrôlés oscillateurs bɛ ni frequency sabatili ka bon nka u ka frequency modulation range ka dɔgɔn; RC voltage-contrôlés oscillateurs bɛ ni frequency stability dɔgɔman ye nka u ka frequency modulation range ka bon; ani LC voltage-contrôlés oscillateurs bɛ bin yɔrɔ dɔ la u ni ɲɔgɔn cɛ.
