Hauv ib RC txuas amplifier , txawm hais tias nws muab peb qhov zoo dua qhov nce voltage, tam sim no nce, bandwidth, kev ncaj ncees amplification, peb yuav tsum txo qis los yog ua kom qhov nce siab tshaj plaws kom ua tiav cov txheej txheem peb xav tau. tawm tswv yim . NEGATIVE Feedback : tawm tswv yim teeb liab yog rho tawm los ntawm sourcesignal.

Ib yam li ntawd, nws raug nug, vim li cas cov lus pom tsis zoo siv hauv amplifiers?

Cov ntawv thov kev tawm tswv yim tsis zoo tuaj yeem txhim kho nws qhov kev ua tau zoo (tau txais kev ruaj ntseg, linearity, zaus teb, stepresponse) thiab txo rhiab heev rau cov kev hloov pauv vim kev tsim khoom lossis ib puag ncig. Vim yog cov txiaj ntsig zoo, ntau amplifiers thiab tswj systems siv negativefeedback.

Tsis tas li ntawd, dab tsi yog qhov zoo ntawm RC txuas amplifier? Qhov zoo ntawm RC Coupled Amplifier Qhov zaus teb ntawm RC amplifier muab qhov nce tsis tu ncua hla ntau qhov ntau zaus, yog li tsim nyog tshaj plaws rau kev siv suab paj nruag. Lub Circuit Court yog yooj yim thiab muaj nqi qis dua vim nws ntiav cov resistors thiab capacitors uas pheej yig.

Ua li no, vim li cas RC coupling siv hauv amplifiers?

Kuj-capacitance ( RC ) kev sib txuas hauv amplifiers feem ntau dav siv mus txuas cov outputof thawj theem mus rau lub tswv yim (piv txwv) ntawm theem ob thiab thiaj li nyob. Qhov no hom ntawm kev sib txuas yog nrov tshaj plaws vim nws yog cheapand muab ib tug tas li amplification dhau ntau yam offrequencies.

Dab tsi yog qhov zoo thiab tsis zoo tawm tswv yim amplifier?

zoo zoo tswv yim yog thaum ib feem ntawm cov zis tau muab rov qab rau cov tswv yim kom cov zis nce ntxiv. Qhov no yog ua los tsim oscillations. thiab negativefeedback yog thaum ib feem ntawm cov zis tau muab rov qab rau cov inputs kom cov zis qis dua. qhov no yog ua kom stabilize qhov nce ntawm ib amplifier.
