Circuit board nyees khawm tuaj yeem pom txhua qhov chaw hauv peb lub neej niaj hnub thiab ua haujlwm, los ntawm cov xov tooj ntawm tes, TV chaw taws teeb tswj mus rau cov keyboards hauv computer. Cov nyees khawm yog qhov nruab nrab tseem ceeb rau kev sib cuam tshuam ntawm peb thiab cov khoom siv.
Lub rooj tsav xwm tseem ceeb yog tsim los ntawm cov keyboards tseem ceeb, txuas txuas, thiab cov khoom tswj. Qhov hloov pauv tseem ceeb yog ib qho tseem ceeb uas ua rau lub teeb liab. Thaum tus yuam sij raug nias, cov hlau sib tiv tauj hauv qhov hloov pauv yuav txuas nrog lub teeb liab kab, yog li hloov lub xeev ntawm Circuit Court. Cov txheej txheem no yuav zoo li yooj yim, tab sis lub hauv paus ntsiab lus yog qhov tseeb heev.
Ua ntej, cia peb saib ntawm cov pob khawm hloov cov qauv. Ib qho tseem ceeb hloov feem ntau muaj lub hauv paus, piston, thiab kev sib cuag. Lub hauv paus yog lub cev tseem ceeb uas nqa tag nrho cov hloov pauv, thaum lub piston plays lub luag haujlwm hauv kev nias thiab popping. Cov kev sib cuag yog ob daim hlau uas tuaj rau hauv kev sib cuag nrog ib leeg thaum lub pob raug nias, tsim ib lub voj voog kaw thiab xa cov teeb liab.
Nyob rau hauv lub rooj tsav xwm tseem ceeb, txhua qhov hloov pauv tseem ceeb muaj qhov sib thooj ntawm qhov sib txuas. Qhov taw qhia soldering yog ib qho tseem ceeb uas txuas tus yuam sij hloov mus rau lub rooj tsav xwm hauv Circuit Court, kom ntseeg tau tias tus yuam sij hloov tuaj yeem ua haujlwm tau zoo thiab xa cov teeb liab. Tsis tas li ntawd, muaj ib lossis ntau cov kab tseem ceeb ntawm lub rooj tsav xwm Circuit Court uas hla tag nrho lub rooj tsav xwm hauv Circuit Court, hu ua kab rov qab. Cov kab tseem ceeb yog lub luag haujlwm rau kev sib koom ua ke thiab xa cov teeb liab los ntawm ntau lub keyboards tseem ceeb, thiab thaum kawg muab lawv los tswj cov khoom siv rau kev ua haujlwm.
Hauv cov khoom siv hluav taws xob niaj hnub no, cov pob hluav taws xob hauv Circuit Court feem ntau cuam tshuam nrog ntau cov channel thiab ntau yam tsim. Qhov no txhais tau hais tias ib lub pob tuaj yeem ua tiav cov haujlwm sib txawv lossis kev ua haujlwm. Qhov no yog ua tsaug rau cov nti embedded ntawm cov khoom siv tswj, uas yog lub luag haujlwm rau kev txheeb xyuas thiab ua cov cim tseem ceeb. Piv txwv li, ntawm cov xov tooj ntawm tes, peb tuaj yeem ua tiav ntau yam haujlwm xws li hu xov tooj thiab xa cov ntawv xov xwm los ntawm cuaj daim phiaj khawm layout.
Tsis tas li ntawd, cov nyees khawm hauv Circuit Court kuj tuaj yeem raug cais los ntawm hom teeb liab. Cov teeb liab tseem ceeb tau muab faib ua cov cim digital thiab cov cim analog. Cov teeb liab digital xa mus rau cov teeb liab nrog tsuas yog ob lub xeev (rau lossis tawm), xws li cov tshuab hloov pauv. Analog signals, ntawm qhov tod tes, muaj kev hloov pauv tsis tu ncua, xws li zawv zawg keyboards. Ntau hom khawm teeb liab yuav tsum tau ua tiav los ntawm kev sib txawv circuits thiab tswj cov khoom.
Zuag qhia tag nrho, cov nyees khawm hauv Circuit Court tsis yog cov nyees khawm yooj yim xwb, lawv zais cov qauv tsim hluav taws xob thiab cov qauv kev ua haujlwm tom qab lawv. Los ntawm kev tsim qauv tsim nyog thiab tsim qauv, khawm lub rooj tsavxwm tuaj yeem ua tiav cov haujlwm nplua nuj thiab ntau hom kev ua haujlwm. Txawm hais tias nws yog cov cuab yeej siv hauv tsev lossis cov khoom siv sib txuas lus siab, cov khawm Circuit Court boards ua lub luag haujlwm tseem ceeb hauv kev muab peb txoj haujlwm yooj yim.
