1. Izicelo Ezinhlelweni Zokuxhumana
Kuzinhlelo zokuxhumana ezingenantambo, ama-voltage-ama-oscillator alawulwayo (VCOs) ayizingxenye ezibalulekile zama-frequency synthesizers. Bangakwazi ukulungisa imvamisa yesiginali yokuphumayo ngesikhathi sangempela ngokuya ngezidingo zephrothokholi yokuxhumana ukuze benze amasignali okushintshashintshashintshayo, amasignali wewashi, namanye amasignali. Lokhu kuvumelana nezimo kubalulekile ekuqinisekiseni ukuzinza nokwethembeka kwezokuxhumana okungenantambo. Isibonelo, kumadivayisi okuxhumana eselula afana nomakhalekhukhwini neziteshi eziyisisekelo, ama-VCO ahlanganiswe kuma-frequency synthesizers ukuze akhiqize amasignali enkampani yenethiwekhi futhi alungise imvamisa yokusebenza njengoba kudingeka.
2. I-Frequency Synthesis kanye Nokuguquguquka
Uma kuhlanganiswa namasekhethi afana nesigaba-amalophu akhiyiwe (PLLs), ama-VCO angenza amasistimu azinzile we-frequency synthesis. Ngokulawula kahle i-voltage yokulawula ye-VCO, imvamisa yesiginali ehlanganisiwe ingalungiswa ngokunembile. Lobu buchwepheshe busetshenziswa kakhulu kumasu okushintshashintshayo afana ne-frequency modulation (FM) kanye ne-frequency shift keying (FSK). Isibonelo, ekudluliselweni kwesignali yomsindo nevidiyo, ukushintshashintsha kwamandla kagesi e-VCO kungalungisa imvamisa yesiginali eshintshiwe, ngaleyo ndlela kuzuze ukudluliswa kwesignali okusebenzayo nokuguquguquka.
3. Ukuhlolwa kanye Nesilinganiso
Emkhakheni wokuhlola nokulinganisa, ama-VCO ngokuvamile asetshenziselwa ukukhiqiza amasignali okuhlola alungisekayo. Lawa masignali angasetshenziswa ezinhlelweni ezihlukahlukene, okuhlanganisa ukukalwa kwefrikhwensi, ukulinganisa imvamisa, nokuhlolwa kokuphendula imvamisa. Isibonelo, ezintweni zokuhlola zikagesi, ama-VCO angakwazi ukukhiqiza imithombo yesignali elungisekayo, asize onjiniyela benze ukuhlaziya isignali, ukulinganisa, noma balingise{2}}izimo zesignali zomhlaba zangempela.
4. Ukuhlanganiswa Komsindo
Ama-Voltage-Ama-Oscillator Alawulwayo (ama-VCO) nawo adlala indima ebalulekile kuma-synthesizer omsindo. Ngokulungisa i-voltage yokulawula ye-VCO, ukuphakama kwesiginali yomsindo kungalungiswa. Lesi sici senza ama-VCO asebenze kabanzi emikhakheni efana nokuhlanganisa umculo nokuhlanganisa umsindo. Isibonelo, ekukhiqizweni komculo we-elekthronikhi, ama-VCO angasetshenziswa ukukhiqiza amanothi ezingoma ezihlukene, ukudala izingoma zomculo ezinothile nezihlukene.
5. I-Radar ne-Sensor Systems
Kuzinhlelo ze-radar nezenzwa, amasiginali azinzile abalulekile ukuze kuqinisekiswe ukusebenza kwesistimu. Ama-VCO ahlinzeka ngokulungiswa kwefrikhwensi okusheshayo nokunembayo, okuvumela amasistimu e-radar ukuthi akhiqize amasiginali we-pulse yamafrikhwensi ahlukahlukene njengoba kudingeka. Lokhu kubalulekile ukuze kuthuthukiswe ukunemba kokutholwa kwe-radar namandla okulwa{2}}nokuphazamiseka. Ngaphezu kwalokho, ezinhlelweni zezinzwa, ama-VCO angasetshenziswa ukukhiqiza amasiginali wereferensi azinzile ukuze asekele imisebenzi ehlukahlukene yokuzwa neyokulinganisa.
6. Ezinye izinhlelo zokusebenza
Ngokungeziwe kulezi zindawo ezishiwo ngenhla, ama-voltage-ama-oscillator alawulwayo (ama-VCO) adlala indima ebalulekile kwamanye amasistimu kagesi amaningi. Isibonelo, -kumasekhethi aphezulu wokudlulisa idatha nokuvumelanisa, ama-VCO ahlinzeka ngamasignali wewashi anembile, aqinisekisa ukusampula okulungile nokutholwa kokusakazwa kwedatha. Ezinhlelweni zokuxhumana ngesathelayithi, ama-VCO abalulekile ekuguquleni imvamisa phakathi kweziteshi ezingaphansi namasathelayithi. Ezinhlelweni zokudlulisa amehlo, amasignali kagesi angase adinge ukushintshwa kwemvamisa ngaphambi kokuba aguqulwe abe amasignali okubona, futhi ama-VCO nawo adlala indima ebalulekile kule nqubo.
