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.

Vim li cas cov lus pom zoo tsis siv hauv op amp?
Tom qab ntawd peb tuaj yeem pom tias cov lus pom zoo tsis tso cai rau lub voj voog ua haujlwm raws li lub suab nrov raws li qhov tso zis hluav taws xob sai sai rau ib qho khoom siv hluav taws xob lossis lwm yam, vim tias nrog cov lus pom zoo "ntau ua rau ntau" thiab "tsawg ua rau tsawg"
Puas yog tus nplaig dov txuas ntxiv lossis tsis txuas ntxiv?
Tus nplaig dov yog ib qho piv txwv ntawm kev hloov pauv tsis tu ncua: koj tuaj yeem yob koj tus nplaig lossis koj ua tsis tau. Cov yam ntxwv uas qhia kev hloov pauv tas mus li feem ntau yog tshwm sim los ntawm txoj kev nyuaj, lossis ntau yam, cov qauv ntawm cov qub txeeg qub teg uas muaj ntau yam sib txawv ntawm cov noob thiab cov yam ntxwv hauv ib puag ncig (piv txwv li, kev noj haus)
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
