Hauv kev ua haujlwm zoo, kev ua haujlwm ntawm kev nqus Circuit Court yog tshem tawm cov teeb liab ntawm qee zaus ntawm lub teeb liab tawm tswv yim. Kev nqus Circuit Court tsim los ntawm LC series resonant circuit. VT1 nyob rau hauv Circuit Court yog thawj theem amplifier, qhov twg U yog lub teeb liab input thiab U yog lub teeb liab tso zis ntawm lub amplifier. Ll thiab Cl tsim ib lub LC series resonant absorption circuit nrog ib tug series resonant zaus ntawm fo, uas yog kev cob cog rua ntawm lub input davhlau ya nyob twg ntawm VT1 thiab hauv av davhlau ya nyob twg.
(1) Lub teeb liab input zaus yog fo. Rau cov teeb liab nrog zaus fo nyob rau hauv lub teeb liab input, vim tib lub resonant zaus li Ll thiab Cl, series Circuit Court ntawm Ll thiab Cl muaj ib tug me me impedance rau nws. Lub teeb liab tawm tswv yim nrog zaus tsib yog hla mus rau hauv av los ntawm Ll thiab Cl thiab tsis tuaj yeem muab ntxiv rau lub hauv paus ntawm VT1. VT1 tsis tuaj yeem nthuav tawm lub teeb liab, thiab tau kawg, tsis muaj teeb liab nrog zaus fo hauv cov teeb liab tso tawm.
(2) Lub teeb liab input zaus siab dua los yog qis dua lub pob zeb. Rau cov teeb liab nrog cov zaus siab dua lossis qis dua fo hauv cov teeb liab tawm tswv yim, vim qhov tsis sib xws ntawm cov resonance frequencies nrog Ll thiab Cl, series Circuit Court ntawm Ll thiab Cl yuav detuned, uas ua rau lub siab impedance. Lub teeb liab tawm tswv yim tsis yog hla mus rau hauv av los ntawm Ll thiab Cl, tab sis yog ntxiv rau lub hauv paus ntawm VT1, amplified los ntawm VT1, thiab tso zis. Los ntawm cov yam ntxwv teb zaus ntawm lub reactor no, nws tuaj yeem pom tau tias tsis muaj lub teeb liab nrog zaus fo nyob rau hauv cov zis teeb liab.
Cov yam ntxwv ntawm series resonant circuit:
1. Thaum lub sij hawm thov yog sib npaug rau nws cov resonant zaus, nws cov Circuit Court impedance nthuav tawm ntshiab tsis kam thiab muaj qhov tsawg kawg nkaus tus nqi. Cov yam ntxwv no yog hu ua lub ntswj lim hauv kev siv tswv yim
2. Thaum cov zaus sab nraud yog siab dua nws cov zaus resonant, lub Circuit Court impedance yog inductive, sib npaug rau inductive coil.
3. Thaum qhov kev thov zaus qis dua nws cov zaus resonant, lub voj voog ua capacitive, sib npaug rau lub capacitor.
Series resonant siab -frequency boost circuit
Lub siab - zaus boost Circuit Court muaj li ntawm LC series circuits. VT1 nyob rau hauv lub Circuit Court tsim ib tug thawj theem ntawm emitter amplifier, thaum Ll thiab C4 tsim ib tug LC series resonant circuit los txhim kho siab - zaus signals. Lub resonant zaus ntawm series resonant Circuit Court ntawm Ll thiab C4 yog tsib, uas yog siab tshaj qhov ntau zaus ntawm kev khiav hauj lwm teeb liab ntawm no amplifier.
Vim qhov tsawg kawg nkaus impedance ntawm Ll thiab C4 circuits thaum lub sij hawm resonance, qhov kev tawm tswv yim tsis zoo raug txo kom tsawg thaum txuas nrog cov emitter tsis zoo tawm tswv yim resistor R4, uas ua rau lub siab tshaj plaws amplification yam nyob rau lub sij hawm no.
Rau cov kev tawm tswv yim nrog cov zaus qis dua li fo, Ll thiab C4 circuits tsis muaj kev txhawb zog rau lawv. Vim hais tias Ll thiab C4 circuits nyob rau hauv lub xeev detuned, lawv impedance yog siab, thiab cov kev tawm tswv yim tsis zoo nyob rau lub sij hawm no yog R4.
Qhov zaus ntawm cov teeb liab tawm tswv yim rau LC parallel resonant Circuit Court yog qhov dav heev, nrog rau cov teeb liab nrog cov zaus sib npaug rau cov zaus resonant. Ntawm ntau cov tswv yim tawm tswv yim ntawm ntau zaus, Circuit Court tsuas yog resonates nrog cov teeb liab ntawm lub resonant zaus, thaum lub sij hawm lub impedance ntawm Circuit Court yog nyob rau hauv siab tshaj plaws. Ib tug resonant circuit muaj ib tug bandwidth. Hauv kev txheeb xyuas Circuit Court, nws tuaj yeem txiav txim siab tias cov teeb liab nyob rau hauv lub zaus band yog amplified los yog amplified tib yam li cov teeb liab ntawm lub resonant zaus.
