Cov lus qhia no qhia yuav ua li cas koj thiaj tuaj yeem ua qhov sib txawv ntawm qhov sib txawv ntawm lub teeb pom kev zoo.

Kev sib cais sib txawv tso cai rau lub zog muab hluav taws xob thiab tshem tawm suab nrov EMI rau ob qhov kev nkag mus.

Qhov Circuit Court no tsis siv lawm. Muaj cov khoom sib txuas resistor IC choj muag hauv internet niaj hnub no.

Ib tus choj tsis sib xws yog tsim los ntawm plaub tus tiv thaiv. Kuv siv ib lub hwj chim los hloov ob lub resistors hauv qab ntawm Circuit Court.

Hmoov tsis zoo, qhov Circuit no tsuas yog tso cai sib piv ntawm qhov hluav taws xob thiab tsuas yog ib feem sib piv ntawm qhov tsis kam rau ob txoj hauv kev. Qhov zoo tshaj plaws Circuit Court yuav suav nrog plaub lub hwj chim.

Koj tuaj yeem ua Circuit 1 lossis Circuit 2.

Lub sensor tuaj yeem yog lub microphone, lub teeb nyob ntawm tus tiv thaiv (LDR), photodiode lossis phototransistor.

Khoom siv

Cheebtsam: duab los qhia, xov hlau.

Circuit 1: 20 kohm potencymeter, 10 kohm resistor - 2.

Circuit 2: 10 kohm potentionmeter, 4.7 kohm resistor - 2.

cov cuab yeej: xaim hluav taws xob, txiab, ob lub zog xa hluav taws xob (koj tuaj yeem siv cov ntsuas hluav taws xob lossis ob peb lub roj teeb).

cov khoom siv tau: lub rooj tsav xwm matrix, cov laug.

cov cuab yeej xaiv tau: soldering hlau, qis zog dual-channel fais fab mov, qhov puncher.

Kauj ruam 1: Tsim Circuit Court

Tsim Circuit Court

Lub Circuit Court yuav tsum txuas nrog lub hwj chim.

Koj tuaj yeem Thevenin qhov ntsuas sib npaug rau qhov Circuit no.

Tam sim no koj tuaj yeem pom tias kev sib tw tiv thaiv tsis yooj yim sua. Koj tuaj yeem txo tus nqi ntawm qhov kev siv hluav taws xob no los ntawm kev siv hluav taws xob ib zaug thiab txuas ob lub zog sib txuas ua ke. Txawm li cas los xij, qhov no yuav swb tag nrho lub hom phiaj ntawm kev sib cais sib cais qhov twg ob txoj kev tawm tsam sib npaug los yog tsawg kawg ib nrab sib phim.

Kauj ruam 2: Ua Circuit Court

Vim tias qhov Circuit Court yog qhov yooj yim heev koj tsis xav tau lub rooj tsav xwm matrix. Txawm li cas los xij, nws tuaj yeem muaj kev nyuab siab me ntsis yog tias cov duab los qhia tuab heev zoo li qhov kuv tau siv.

Koj tuaj yeem xuas qhov nrog txiab.

Kuv siv lub qub 20 kohm kuj sib txawv resistor los ntawm cov khoom siv hluav taws xob qub.

Kauj Ruam 3: Xeem Lub Circuit Court

Kauj Ruam 1: Txuas ob lub hwj huam nkag mus, txuas ob lub xov hlau daj ua ke thiab txuas mus rau thawj lub zog xa hluav taws xob.

Kauj Ruam 2: Siv cov lus luv los tiv thaiv kev cuam tshuam ntawm EMI suab nrov.

Sib piv Thevenin qhov hluav taws xob

Kauj Ruam 3: Hloov pauv lub hwj chim kom txog rau thaum qhov hluav taws xob ntawm ob qho kev tso tawm sib npaug.

Kev ntxub ntxaug

Kauj Ruam 4: Hloov pauv lub zog hluav taws xob txhawm rau txhawm rau ntsuas lub ntsuas.
