Akapsa zambiri amapezeka m'madera amagetsi. Iwo kumagwira ntchito za mfundo zambiri, kuchita ntchito zosiyanasiyana, kapena akhoza akuyendera pa zinthu zosiyanasiyana, koma mfundo ya ntchito n'chimodzimodzi. Nkhani wapadera ndi otchedwa Schmitt choyambitsa, bwino kutsimikiziridwa ntchito. Izi kusinthidwa zothandiza dera choyambirira mu nthawi yochepa chapeza wotchuka kwambiri pakati okonza.
Pali zosiyanasiyana options kukhazikitsa mfundo izi: choyambitsa transistors, amplifiers ntchito, tchipisi digito, etc. Mwachitsanzo, taonani digito Schmitt choyambitsa mfundo zomwe zingatithandize ambiri kuthana ndi chipangizo ichi. Tiyerekeze kuti ife cholinga dera limene lili zolowetsa awiri ndi zotuluka awiri. Pamene osakaniza athandizira amam'dziŵitsa 1-0, 0-1 kapena kusintha linanena bungwe boma. Nthawi zina zonse, chipangizo oterowo adzakumbukira boma wapachiyambi. Zingaoneke, ndipo apa Schmitt choyambitsa, nanga lingaliro lake?
Pambuyo kuyambitsa chipangizo comparator ndi athandizira ndi wopandamalire chiletso koyefishienti, ndi lingaliro kulenga zipangizo yaing'ono kuti amatha kuloweza akuyambira pachiyambi. Woyamba anali anasonkhana pa Schmitt choyambitsa comparator. A sangathe chachikulu chiwembu izi ankaona ngati kudzipheralo chizindikiro kulowerera dera a hule. sangathe Izi yathetsedwa ndi Schmitt pambuyo kumayambiriro hysteresis cha machitidwe a dera la. Pankhaniyi, pamwamba enaake izo masiwichi ntchito chipangizo, koma kubwerera ku dziko choyambirira izo zinali zotheka ngati lophimba kumbuyo. M'mawu ena, kumayambiriro hysteresis cha machitidwe a dera la zapangitsa kuti ntchito zake odekha. Kusiyitsa "zophukiranso" pa kuchoka, anali inertia choncho odalirika ntchito. chipangizo oterowo amatchedwa Schmitt choyambitsa, ndipo ili ndi dzina la Mlengi wake.
Ntchito chipangizo digito tafotokozazi akukumana zofunika zimenezi. Iye ali pakhomo ena. Pali magulu a voteji aliyense wa mayiko - "ziro" ndi "munthu". Izi wangwiro Schmitt choyambitsa. Ngati ife timathandiza akuchedwa yaing'ono kusinthitsa, ndi zotheka kuti tichotse ambiri phokoso amaganizira ndi ntchito zipangizo zambiri.
Field ntchito zipangizo amenewa ndi yaikulu ndithu iwo kuwayang'anira boma la masensa ntchito mu machitidwe wakubayo wafika Alamu kupanga makina, ndi madera a pakompyuta zolinga zosiyanasiyana. Mwina ambiri a ife monga makina olowetsa ntchito mphatso? Pofuna kupewa yaying'ono-lophimba debouncing mu kudutsa chizindikiro kudzera wosinthanitsa ndi amayikidwa mu Schmitt choyambitsa dera. Amaonetsetsa ntchito khola la makina olowetsa lonse.
Ndi chitukuko cha zigawo zikuluzikulu ndi luso kupanga zamakono pali azimuth azilandira kwa akapsa miniaturization ndi bwino ntchito yawo.
