Filter capacitance muaj nuj nqi: siv nyob rau hauv lim Circuit Court ntawm lub capacitor yog hu ua lim capacitor, nyob rau hauv lub hwj chim mov lim thiab ntau yam lim circuits siv no capacitor Circuit Court, lim capacitor yuav yog ib tug tej zaus band ntawm cov teeb liab los ntawm tag nrho cov teeb liab tshem tawm.
Decoupling capacitor muaj nuj nqi, siv nyob rau hauv lub decoupling Circuit Court ntawm lub capacitor yog hu ua decoupling capacitor, nyob rau hauv lub multi-theem amplifier DC voltage mov circuit siv no capacitor circuit, decoupling capacitor kom tshem tawm cov teeb meem tsawg zaus crosslinks ntawm txhua theem amplifier.
High-frequency dissipation capacitance muaj nuj nqi: siv nyob rau hauv high-frequency dissipation Circuit Court capacitors hu ua high-frequency dissipation capacitance, nyob rau hauv lub suab tsis zoo tawm tswv yim amplifier, nyob rau hauv thiaj li yuav dissipate qhov ua tau high-frequency self-excitation, siv xws li capacitor circuits, hauv kev txiav txim kom tshem tawm cov amplifiers tuaj yeem tshwm sim ntau zaus whistling.
Resonant capacitor muaj nuj nqi: siv nyob rau hauv LC resonant Circuit Court capacitor hu ua resonant capacitor, LC parallel thiab series resonant circuits xav tau lub capacitor Circuit Court.
Bypass capacitor muaj nuj nqi: siv nyob rau hauv bypass Circuit Court ntawm lub capacitor yog hu ua bypass capacitor, lub Circuit Court yog tias koj yuav tsum tshem tawm ib tug tej yam band ntawm lub teeb liab ntawm lub teeb liab, koj muaj peev xwm siv lub bypass capacitor Circuit Court, raws li tshem tawm cov teeb liab zaus sib txawv, muaj ib tug tag nrho-frequency domain (tag nrho cov AC signals) bypass capacitor circuits thiab high-frequency bypass capacitor circuits.
Neutralization capacitor muaj nuj nqi: Capacitors siv nyob rau hauv neutralization circuits yog hu ua neutralization capacitor. Cov neutralizing capacitor circuits yog siv nyob rau hauv xov tooj cua high-frequency thiab intermediate-frequency amplifiers, thiab TV high-frequency amplifiers kom tshem tawm nws tus kheej excitation.
Timing Capacitor Function: Capacitor siv nyob rau hauv lub sij hawm circuits yog hu ua lub sij hawm capacitor. Timing capacitor circuits yog siv nyob rau hauv circuits uas yuav tsum tau tswj lub sij hawm los ntawm capacitor them thiab tawm, thiab lub capacitor plays lub luag hauj lwm ntawm kev tswj qhov luaj li cas ntawm lub sij hawm tas li.
Integral Capacitor Function: Lub capacitor siv nyob rau hauv ib qho hluav taws xob Circuit Court yog hu ua ib qho capacitor. Nyob rau hauv lub synchronous sib cais Circuit Court ntawm tej zaum scanning, no ib tug capacitor Circuit Court yog siv los tshem tawm lub teb synchronous teeb liab ntawm lub teb composite synchronous teeb liab.
Differential capacitance muaj nuj nqi: lub capacitor siv nyob rau hauv txawv Circuit Court yog hu ua txawv capacitance. Nyob rau hauv lub trigger circuit thiaj li yuav tau txais lub sab saum toj trigger teeb liab, qhov txawv capacitor Circuit Court, thiaj li yuav tau txais lub sab saum toj pulse trigger teeb liab los ntawm tag nrho cov hom (feem ntau yog daim duab mem tes) teeb liab.
Compensation Capacitor Function: Lub capacitor siv nyob rau hauv cov nyiaj them nqi hluav taws xob hu ua them nyiaj capacitor. Nyob rau hauv lub bass them nyiaj Circuit Court ntawm lub lawj, qhov tsawg zaus them nyiaj capacitor Circuit Court yog siv los txhim kho cov teeb liab tsawg zaus hauv cov teeb liab playback, thiab kuj tseem muaj qhov them nyiaj ntau zaus capacitor circuit.
Bootstrap Capacitor Function: Lub capacitor siv nyob rau hauv lub bootstrap Circuit Court yog hu ua bootstrap capacitor, thiab feem ntau siv OTL lub hwj chim amplifier tso zis theem circuits siv xws li bootstrap capacitor circuits los txhim kho qhov zoo ib nrab-lub sij hawm amplitude ntawm lub teeb liab nyob rau hauv ib tug me me npaum li cas ntawm txoj kev. zoo tswv yim.
Crossover capacitance muaj nuj nqi: lub capacitor nyob rau hauv lub crossover Circuit Court yog hu ua crossover capacitor, nyob rau hauv tus neeg hais lus crossover circuit ntawm tus neeg hais lus, siv crossover capacitance Circuit Court, thiaj li yuav ua rau cov neeg hais lus ntau zaus ua haujlwm nyob rau hauv high-frequency band, mid- Cov neeg hais lus ntau zaus ua haujlwm hauv nruab nrab ntawm cov kab hluav taws xob, thiab cov neeg hais lus tsawg zaus ua haujlwm hauv cov kab hluav taws xob tsawg.
Load capacitance muaj nuj nqi: Nws yog qhov zoo sab nraud capacitance uas txiav txim siab lub resonant zaus ntawm lub load ua ke nrog quartz siv lead ua resonator. Tus qauv qhov tseem ceeb ntawm load capacitance yog 16pF, 20pF, 30pF, 50pF thiab 100pF. Lub load capacitance tuaj yeem hloov kho raws li qhov xwm txheej tshwj xeeb, thiab los ntawm kev kho lub load capacitance, kev khiav hauj lwm zaus ntawm resonator tuaj yeem hloov kho rau tus nqi nominal. Digital multimeter nyob rau hauv lub capacitance muaj nuj nqi lub luag hauj lwm muaj ntau ntau yam, feem ntau yog nyob ntawm tus electrician nrog ib tug digital multimeter * yuav tsum ntsuas cov khoom dab tsi.
