ADCs ua raws li ib ntus thaum hloov cov cim analog rau digital. Lawv thawj zaug ua piv txwv lub teeb liab, tom qab ntawd ntsuas nws los txiav txim siab qhov kev daws teeb meem ntawm lub teeb liab, thiab thaum kawg teeb tsa binary qhov tseem ceeb thiab xa mus rau lub kaw lus nyeem cov teeb liab digital. Ob qhov tseem ceeb ntawm ADC yog nws qhov piv txwv tus nqi thiab kev daws teeb meem.
Tus txheej txheem ntawm analog rau digital hloov pauv yog dab tsi?
Analog-rau-digital conversion yog tus txheej txheem hluav taws xob uas hloov pauv tsis tu ncua (analog) teeb liab hloov, yam tsis hloov nws cov ntsiab lus tseem ceeb, mus rau ntau theem (digital) teeb liab. … Cov cim digital yooj yim tshaj plaws tsuas muaj ob lub xeev, thiab hu ua binary.
Koj yuav hloov cov voltage analog rau digital voltage li cas?
Analog-to-Digital Converters (ADCs) hloov pauv qhov voltage analog rau tus lej binary (series ntawm 1's thiab 0's), thiab tom qab ntawd nws thiaj li mus rau tus lej digital (piv txwv. 10) rau kev nyeem ntawv ntawm ib lub 'meter', saib, lossis daim ntawv qhia. Tus lej ntawm tus lej binary (ntsis) uas sawv cev rau tus lej digital txiav txim siab ADC daws teeb meem.
Kuv puas tuaj yeem siv tus pins digital ua analog?
Tus lej tus lej yog nws qhov kev ntsuas nkaus xwb. Lub Arduino tsis muaj digital-rau-analog converter (DAC) built-in, tab sis nws tuaj yeem ua pulse-width modulation (PWM) cov teeb liab siv los ua tiav qee qhov analog. tso zis ua haujlwm. Kev ua haujlwm analogWrite(pin, tus nqi) yog siv los tso tawm PWM teeb liab.
Nws yog ib qho piv txwv ntawm analog raudigital converter?
Digital analog converter yog dab tsi? Cov zis ntawm lub microphone, qhov hluav taws xob ntawm lub photodiode lossis lub teeb liab ntawm lub ntsuas hluav taws xob yog cov piv txwv ntawm cov txiaj ntsig analog uas yuav tsum tau hloov pauv kom lub microprocessor tuaj yeem ua haujlwm nrog lawv.
