1. Cov ntawv thov nyob rau hauv cov tshuab sib txuas lus
Hauv kev sib txuas lus wireless lub tshuab, voltage - tswj oscillators (VCOs) yog qhov tseem ceeb ntawm cov khoom sib xyaw. Lawv tuaj yeem kho cov zaus ntawm cov paib tawm hauv lub sijhawm tiag raws li cov kev xav tau ntawm kev sib txuas lus los tsim cov paib kev sib txuas lus los tsim cov paib kev sib txuas lus los tsim cov paib kev sib txuas lus los tsim cov paib kev sib txuas lus, moos teev npe, thiab lwm lub cim. Qhov kev hloov pauv no yog qhov tseem ceeb los ua kom muaj kev ruaj ntseg thiab kev ntseeg tau ntawm kev sib txuas lus wireless. Piv txwv li, hauv cov xov tooj ntawm tes xws li lub xov tooj txawb thiab cov chaw nres tsheb hauv paus kom tsim cov khoom siv hluav taws xob thiab kho cov kev ua haujlwm raws li xav tau.
2. Ntau zaus synthesis thiab kev hloov kho
Thaum ua ke nrog cov circuits xws li theem - Xauv cov loops (PLCOS tuaj yeem tsim cov khoom ruaj khov hluavtaws hluav taws xob synthesis. Los ntawm kev tswj hwm kom meej Cov tshuab no tau siv dav hauv cov txheej txheem kev hloov kho xws li zaus ua haujlwm (FM) thiab zaus Hloov Khoom Hloov (FSK). Piv txwv li, hauv audio thiab video teeb liab teeb liab sib kis, sib txawv VCO cov teeb liab muaj zog tuaj yeem hloov kho lub cim thiab kev ua tiav cov teeb liab kev sib kis thiab kev ua tiav.
3. Kuaj thiab ntsuas
Hauv kev ntsuas ntsuas thiab ntsuas kev ntsuas, VCOs feem ntau siv los tsim cov cim ntsuas cov cim tau. Cov phiajcals no tuaj yeem siv tau ntau yam kev siv, suav nrog kev ntsuas ntsuas zaus, ntsuas zaus thiab kev sim ntsuas zaus. Piv txwv li, hauv cov khoom siv rau hluav taws xob, VCOs tuaj yeem tsim cov chaw ntsuas kev hloov kho, ntsuas cov teeb meem, ntsuas hluav taws xob, lossis simulate} lub teeb liab teeb liab.
4. Suab synthesis
Voltage - tswj oscillators (VCOs) tseem ntaus lub luag haujlwm tseem ceeb hauv lub suab synthesizers. Los ntawm kev kho lub VCO tswj hluav taws xob, lub suab ntawm lub teeb liab suab tuaj yeem hloov kho. Cov xeeb ceem no ua rau VCOs dav siv nyob rau hauv teb xws li suab paj nruag hluavtaws thiab suab synthesis. Piv txwv li, hauv cov suab paj nruag hauv cov suab paj nruag los tsim tau los tsim cov ntawv sau ntawm cov suab sib txawv, tsim cov suab paj nruag sib txawv.
5. Lub Nruab Nrab thiab Sensor Systems
Nyob rau hauv radar thiab sensor nruab, ruaj khov zaus phiaj xwm yog qhov tseem ceeb rau kev ua haujlwm. VCOs muab kev hloov kho sai thiab meej haum, ua kom haum dua kho kom haum, ua kom haum radar tshuab los tsim cov cim mem tes ntawm cov chaw nquag ua raws li xav tau. Qhov no yog qhov tseem ceeb rau kev txhim kho cov radar retectacy thiab anti - kev cuam tshuam nrog lub peev xwm. Tsis tas li ntawd, nyob rau sensor nruab, vcos tuaj yeem siv los tsim cov cim ruaj khov los txhawb ntau yam kev xav thiab ntsuas cov haujlwm.
6. Lwm cov kev siv
Ntxiv rau cov chaw ua haujlwm ntawm cov chaw, voltage - tswj oscillators (VCOs) Ua ib lub luag haujlwm tseem ceeb hauv ntau lwm lub tshuab hluav taws xob. Piv txwv li, nyob rau hauv high - ceev cov ntaub ntawv kis thiab synchronization ci cim, kom tau sam hwm kom raug thiab rov qab ntawm cov ntaub ntawv ntws. Hauv satellite kev sib txuas lus cov tshuab, vcos yog qhov tseem ceeb rau kev zaus kev sib tw ntawm cov chaw nres tsheb thiab satellites. Hauv kev kis kho qhov muag lub tshuab, hluav taws xob cov cim yuav xav tau cov kev hloov kho hluav taws xob ntau zaus ua ntej hloov kho cov cim kho qhov tseem ceeb hauv cov txheej txheem no.
