Schmitt txhais cov khoom siv feem ntau yog siv rau hauv cov ntawv thov txias kom tshem tawm cov suab nrov ntawm cov cim siv hauv digital circuits, tshwj xeeb tshaj yog cov neeg kho tshuab kev sib cuag bounce hauv keyboards.
Dab tsi yog qhov zoo ntawm Schmitt ua rau sib piv?
Qhov kom zoo dua ntawm kev tawm tswv yim zoo yog tias qhov tshwm sim ntawm qhov sib piv Schmitt trigger Circuit Court yog tiv thaiv kom tsis txhob cuam tshuam los ntawm lub suab nrovlossis maj mam hloov cov tswv yim tawm tswv yim nyob rau hauv hysteresis band ua kom muaj cov teeb liab tso tawm kom huv. raws li cov op-amp piv cov zis tawm tsuas yog tshwm sim ib zaug.
Vim li cas Schmitt trigger hu ua regenerative comparator?
A Schmitt trigger circuit tseem hu ua regenerative comparator circuit. Lub circuit yog tsim los nrog cov lus pom zoo thiab yog li yuav muaj qhov rov ua dua tshiab uas yuav ua rau cov zis hloov pauv qib. … Nws yog ib qho kev sib piv inverting circuit nrog cov lus pom zoo.
Schmitt ua li cas txo suab nrov?
Thaum cov input voltage tshaj Vhigh, cov zis hloov mus rau qib siab. Tsuas yog thaum lub input voltage poob qis dua V low (uas yuav tsum qis dua Vhigh), cov zis hloov rov qab rau nws low state. Hom kev txo suab nrov no yog siv rau hauv cov khoom siv ntawm I²C tsheb npav.
UTP thiab LTP yog dab tsi hauv Schmitt ua?
Nyob rau hauv Schmitt trigger, qhov voltages uas cov zis hloov ntawm +vsat rau–vsat los yog vice versa yog hu ua sab saum toj taw tes (UTP) thiab qis trigger point (LTP). qhov txawv ntawm ob lub ntsiab lus mus txawv tebchaws yog hu ua hysteresis.
