Qhov sib txawv ntawm cov khoom siv hluav taws xob digital thiab analog fais fab mov
Qhov sib txawv tseem ceeb ntawm cov khoom siv hluav taws xob digital thiab cov khoom siv hluav taws xob analog yog nyob hauv kev tswj hwm thiab kev sib txuas lus. Hauv cov ntawv thov uas yooj yim rau siv thiab xav tau kev hloov pauv me me, cov khoom siv hluav taws xob analog muaj qhov zoo dua vim tias lawv cov phiaj xwm tuaj yeem ua tiav los ntawm kev kho vajtse ruaj khov. Hauv kev siv cov txheej txheem kev ua haujlwm siab nrog ntau yam tswj tau, nrawm dua lub sijhawm teb ceev, thiab xav tau ntau qhov kev tswj hwm lub zog analog, cov khoom siv hluav taws xob digital muaj qhov zoo.
Tsis tas li ntawd, nyob rau hauv ntau txoj kev lag luam, piv rau cov khoom siv hluav taws xob analog, cov khoom siv hluav taws xob digital yog siv los ntawm software programming rau ntau yam kev siv. Nws scalability thiab reusability pab kom cov neeg siv tau yooj yim hloov cov kev ua hauj lwm tsis thiab optimize lub hwj chim systems. Los ntawm kev tiv thaiv overcurrent thiab tswj lub sijhawm tiag tiag, nws tuaj yeem txo tus naj npawb ntawm cov khoom siv peripheral.
Cov khoom siv hluav taws xob digital yog tswj los ntawm ob qho tib si DSp thiab MCU. Kev hais lus zoo, lub zog hluav taws xob tswj hwm los ntawm DSp tau txais cov txheej txheem lim dej digital, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob zoo, muaj cov lus teb ceev ceev ntawm lub sijhawm, thiab kev ua haujlwm ruaj khov zoo dua li lub zog tswj los ntawm MCU.
Dab tsi yog cov txiaj ntsig ntawm cov khoom siv hluav taws xob digital? Nws yog thawj programmable, thiab tag nrho cov haujlwm xws li kev sib txuas lus, nrhiav pom, telemetry, thiab lwm yam tuaj yeem siv los ntawm software programming. Tsis tas li ntawd, cov khoom siv hluav taws xob digital muaj kev ua haujlwm siab thiab kev ntseeg siab, ua rau lawv hloov tau yooj yim.
Cov khoom siv hluav taws xob digital tsis yog cov mos txwv khawv koob uas ua rau lub zog analog tsis tau. Ob qho tib si analog thiab digital zog qhov chaw yuav muaj nyob thiab ua ke sib haum xeeb. Yog tias tsis muaj kev tswj hwm digital ntxiv lawm, ces qhov khoom siv hluav taws xob analog yog qhov kev xaiv zoo tshaj plaws. Ntawm qhov tsis sib xws, nyob rau hauv cov txheej txheem nyuaj uas muaj ntau qhov kev tswj hwm nruj nruj, kev saib xyuas, kev sib txuas lus cov ntaub ntawv, thiab hloov pauv hloov pauv yuav tsum tau ua, thiab cov kev daws teeb meem digital tuaj yeem ua tau zoo dua lawv lub luag haujlwm. Hmoov zoo, qhov kev taw qhia ntawm digital power control optimized microprocessors thiab tshwm sim ntawm cov cuab yeej tshiab thiab kev cob qhia tuaj yeem ua rau cov neeg tsim qauv xaiv cov kev daws teeb meem zoo tshaj plaws rau lawv cov ntawv thov tam sim no.
