Daim duab kos duab yog kos duab ntawm cov khoom siv hluav taws xob los ntawm cov cim hauv Circuit Court, uas piav qhia meej txog kev sib txuas thiab kev taw qhia ntawm txhua yam, cov lus piav qhia ntawm txhua tus pin thiab qee cov ntaub ntawv xeem.
PCB daim duab qhia txog kev nthuav dav ntawm kev sib tw ntawm lub rooj tsavxwm, qhov chaw ntawm cov khoom siv, thiab lwm yam. Saib ntawm daim duab kos duab ua ntej saib cov khoom siv hluav taws xob, kom nkag siab txog lub Circuit Court nyob rau hauv rooj plaub ntawm cov khoom siv hluav taws xob ua haujlwm, AC lossis DC, ib leeg. los yog ntau yam khoom siv hluav taws xob thiab qib voltage. Tom qab pom meej ntawm kev faib hluav taws xob, thawj qhov sib txawv ntawm cov digital circuits, lossis analog circuits. Analog circuits saib cov teeb liab nrhiav tau, xam qhov chaw ntawm lub teeb liab, muaj RF, suab, txhua yam ntawm sensors, instrumentation los yog lwm yam circuits, thiab lwm yam..Tam sim seb lub teeb liab yog AC, DC los yog mem tes, thiab seb nws yog. voltage-based lossis tam sim no-based.
Txheeb xyuas qhov ua haujlwm ntawm lub voj voog tom ntej kom paub seb nws puas yog demodulation, amplification, shaping lossis them nyiaj thiab lwm yam haujlwm. Thaum kawg, saib ntawm qhov tso zis hluav taws xob, txawm tias nws yog modulated lossis tsav. Cov digital Circuit ces tsuas yog txheeb xyuas qhov kev ua haujlwm thiab lub luag haujlwm ntawm lub voj voog.
Yuav kom nkag siab txog lub rooj tsav xwm Circuit Court, koj yuav tsum xub nyeem nws cov hluav taws xob schematic. Peb yuav tsum paub txog txoj hauv kev uas cov khoom siv hluav taws xob tau sau npe, lub hauv paus ntsiab lus ntawm kev ua haujlwm, thiab qee qhov sib xyaw ntawm cov khoom siv ib txwm muaj thiab lub luag haujlwm ua haujlwm hauv qhov qub Circuit Court thiab lwm yam kev paub, thiab tom qab ntawd txheeb xyuas lub rooj tsavxwm, koj tuaj yeem nyeem nws txoj haujlwm ua haujlwm thiab qee qhov. yuav tsum paub qhov xwm txheej sai sai.
Kev tshuaj xyuas ntawm cov khoom siv hluav taws xob hauv hluav taws xob, txhawm rau nrhiav cov ntsiab lus tseem ceeb ntawm txhua lub voj voog hluav taws xob, kom paub qhov kev sib txuas ntawm cov hluav taws xob ntau ntawm txhua qhov hluav taws xob hauv hluav taws xob, thiab thaum kawg qhov tso tawm thiab kev tawm tswv yim lossis kev ua haujlwm ntawm tag nrho Circuit Court.
Tag nrho cov Circuit Court yog tsim los ntawm txhua chav tsev Circuit Court, chav tsev circuits tsim cov teeb liab ua cov ceg ntoo nrog qee yam haujlwm, thiab tom qab ntawd cov ceg ntoo no tsim tag nrho lub voj voog. Ua ntej, koj yuav tsum paub seb lub luag haujlwm ntawm daim duab kos duab koj tab tom saib yog dab tsi, hom Circuit Court nws yog, txawm tias nws yog suab, video, digital, lossis hybrid circuit; tom qab ntawd siv cov kev paub zoo sib xws ntawm chav ntsuas hluav taws xob los txhais cov circuits no; Nyob rau tib lub sij hawm los soj ntsuam AC teeb liab theem, DC theem, DC ib feem ntawm lub voj voog yog lub hauv paus rau kev ua haujlwm ntawm lub voj voog, lub teeb liab AC yog ib txwm nyob hauv DC Circuit Court kom tau txais kev tsim nyog, Circuit Court tsis muaj lub xeev DC zoo, tsis tuaj yeem ua haujlwm zoo.
Tsis tas li los ntawm qib zaus, lub amplifier nce qib ntawm kev tsom xam, cov cim zaus sib txawv hauv kev ua haujlwm hauv Circuit Court, vim yog cov khoom siv tsis-linear hauv Circuit Court, yuav muaj cov txiaj ntsig sib txawv rau cov zaus sib txawv, amplifiers rau ntau zaus ntawm cov teeb liab kuj txawv. amplification muaj peev xwm, lub Circuit Court yuav raug tsim los rau qhov yuav tsum tau lub teeb liab zaus rau lub hom phiaj ua, thiaj li ua tiav cov kev xav tau ntawm lub tshuab. Tom qab ntawd muaj kev tsom xam ntawm kev sib raug zoo ntawm txhua chav tsev hauv Circuit Court, nrog rau kev sib raug zoo ntawm cov tswv yim thiab cov zis ntawm lub tsev hauv Circuit Court. Cov kev hloov pauv dab tsi yog tsim los ntawm AC teeb liab tom qab dhau los ntawm cov circuits, thiab lwm yam.
Tom qab nkag siab txog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm txhua ceg hauv Circuit Court, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tag nrho lub tshuab tuaj yeem txheeb xyuas. Piv txwv li, cov kab rov qab mem tes ntawm kab tso zis hluav taws xob ntawm lub TV teeb yog siv rau hauv cov xim txiav txim siab Circuit Court, thiab muaj cov teeb liab sib cuam tshuam ntawm cov kab hluav taws xob hluav taws xob thiab cov xim decoding Circuit Court, yog li cov ceg no tuaj yeem nkag siab zoo li lwm yam. ntawm chav tsev Circuit Court thiab tom qab ntawd txheeb xyuas.
Txhawm rau ua tiav kev tsim hluav taws xob los ntawm kev txheeb xyuas lub voj voog schematic daim duab pib, koj yuav tsum xub nkag siab lub pinout thiab lub luag haujlwm tseem ceeb ntawm cov nti uas yuav tsum tau ua, uas yog qhov tsim nyog rau kev nkag siab zoo dua ntawm kev ua haujlwm ntawm lub voj voog, kom nws tuaj yeem siv rau koj tus kheej Circuit Court, uas yog conducive rau Circuit Court trimming thiab expansion.
Thaum ua qhov kev ntsuam xyuas hauv Circuit Court, koj yuav tsum muaj kev nkag siab dav dav ntawm Circuit Court schematic thiab faib cov khoom siv sib txawv, xws li lub zog module, xws li module, nco module, suab module, GPRS module, thiab lwm yam. ib qho, thiab qhov kawg kev sib koom ua ke saib yuav ua rau kev nkag siab dav dav ntawm cov haujlwm kom ua tiav los ntawm Circuit Court. Thaum tsim ib lub voj voog, nws yog qhov zoo tshaj plaws kom paub cov ntsiab lus ntawm cov qauv siv los yog feem ntau siv cov khoom siv hluav taws xob, xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov cim xeeb, thiab lwm yam., feem ntau siv cov chips, xws li: 7805, 7812, thiab lwm yam.
Thaum tsim ib lub voj voog, faib lub voj voog uas koj xav tsim rau hauv ntau lub modules, tsim lawv hauv cov schematics sib txawv, thiab thaum kawg sib xyaw ua ke. Thaum muaj cov teeb liab tawm tswv yim rau hauv Circuit Court, nws yog ib qho tseem ceeb kom muaj kev kwv yees kwv yees ntawm qhov voltage thiab tam sim no yuav nyob ntawm txhua qhov taw qhia. Rau circuits nrog amplifiers thiab RLCs, nws nyob ntawm seb lub Circuit Court yog oscillating circuit, amplifying circuit, los yog ib tug shaping circuit, thiab lwm yam.
Kev tsom xam ntawm qhov chaw ua haujlwm zoo li qub ntawm transistors, kev soj ntsuam ntawm lub xeev kev ua haujlwm, thiab lwm yam, kev lim dej ntawm cov capacitors, inter-theem coupling, high-frequency, low-frequency circuits, thiab lwm yam. Feem ntau peb siv tsawg zaus circuits, siab zaus feem ntau yog siv ntau dua hauv kev sib txuas lus.
