Ashaywe ngokuvamile itholakala e kagesi. Bazibandakanye umsebenzi ISIZINDA eziningi, enza ezihlukahlukene imisebenzi, noma kungenzeka ukusebenza izakhi ezahlukene, kodwa isimiso wokusebenza sawo siyafana. Ikesi ekhethekile iyona okuthiwa Schmitt inhlamvu, kahle kungase kutholakale ukusebenza. Lokhu ukuguqulwa ewusizo kwe-circuit yasekuqaleni ngesikhathi esifushane iye yatha- omkhulukazi phakathi abaklami.
Kunezindlela ezihlukahlukene ongakhetha ukuze lelisu lo mbono: inhlamvu transistors, yokukhulisa umsindo tekusebenta, chips digital, njll Njengoba isibonelo, cabanga digital Schmitt inhlamvu, isimiso zazo kuzosisiza ngokuvamile ukubhekana nale divayisi. Ake sithi siye eklanyelwe wesifunda has okokufaka ezimbili kanye Imiphumela ezimbili. Lapho inhlanganisela okokufaka kuwuphawu 1-0, 0-1 noma ushintsho esimweni okukhiphayo. Kuzo zonke ezinye izimo, leli thuluzi uzokhumbula esimweni saso sokuqala. Kunengqondo, futhi lapha Schmitt inhlamvu, futhi yini umbono wakhe?
Ngemva kokusungulwa kudivayisi comparator nge uvo kanye elingapheli izivimbelo Coefficient, futhi umbono ukudala kumadivayisi amancane ukuthi bayakwazi ngekhanda ukulandelana yasekuqaleni. Eyokuqala yabuthelwa kwi Schmitt inhlamvu comparator. A kusimo enkulu yalesi sikhwama kubhekwe njengendlela nokucupha isignali drift esifundeni ka inhlamvu. Lokhu kusimo sekuqediwe futhi Schmitt emva kusungulwa hysteresis ekuqhubeni circuit. Kulokhu, ngenhla ezingeni elithile ke sekuqalile ukusebenza idivayisi, kodwa ukubuyela kuhulumeni sokuqala kwaba kungenzeka kuphela uma inkinobho emuva. Ngamanye amazwi, ukwethulwa hysteresis ekuqhubeni circuit kuye kwaholela ukusebenza kwawo izinze. Imise "ebuyile" at the ophumayo, kwaba inertia ngakhoke okuthembekile ukusebenza. idivayisi okunjalo kwezinkolo kubizwa ngokuthi i-Schmitt inhlamvu, futhi iqanjwe kumdlali.
Umsebenzi idivayisi digital ezichazwe ngenhla ihlangabezana nalezi zimfuneko. Anakho embundwini ezithile. Kukhona amazinga voltage ngamunye uthi - "zero" futhi "omunye". Lona ephelele Schmitt inhlamvu. Uma sethula ukubambezeleka ezincane usuke, kungenzeka ukuqeda iningi umsindo ngokuvamile uhlanganiswa umsebenzi kumadivayisi amaningi.
Field kwesicelo amadivayisi esinjalo kubaluleke ngempela ebanzi kuqashwe isimo izinzwa elisetshenziswa umgqekezi alamu izinhlelo zokukhiqiza ezenzakalelayo, ne izifunda ngogesi ngezinjongo ahlukahlukene. Mhlawumbe abaningi bethu zihlanganisa slot machines usebenzisa amathokheni? Ukuvimbela i-micro-switch debouncing ekudluliseleni uphawu ngokusebenzisa Tjhugulula lihlelwe Schmitt inhlamvu wesifunda. Yena kuqinisekisa operation esitebeleni of lonke slot machine.
With ukuthuthukiswa izingxenye kanye nokukhiqiza ubuchwepheshe zobuchwepheshe kunomkhuba engaguquki maqondana trigger miniaturization futhi sithuthukise ukusebenza kwabo.
