Imiphumela yokulinganisa ithonya ngokuqondile ukukhethwa kwezinto kanye nokwakheka kwesistimu.Ukulahlekelwa kwe-hysteresis ngokweqile kungase kukhuphule ukukhiqizwa kokushisa, kuyilapho ama-threshold akhethwe kabi angase anciphise ukusebenza ngendlela efanayo.

Ukuthuthukisa i-Hysteresis ku-Electronic Design

I-Hysteresis vs Non-Hysteretic Systems

Isici	I-Hysteresis	I-Non-Hystertic
Umsindo Ukungavikeleki	Phezulu	Phansi
Ukuzinza	Okungcono	Ukuzinza okuncane
Ukushintsha Imvamisa	Phansi	Phezulu
Ukuzwela	Phansi	Phezulu
Amanga Ukucupha	Yehlisiwe	Okuvame kakhulu
Isikhathi Eside Ukwethembeka	Okungcono	Yehlisiwe

Lesi siqhathaniso sibonisa ukuthi kungani i-hysteresis yethulwa ngamabomu ezinhlelweni eziningi ezisebenzayo.

Izinto ezimbalwa zithonya ukuziphatha kwe-hysteresis, okuhlanganisa umsindo kagesi, izinga lokushisa lokusebenza, i-ion v ariat ion, isivinini sokushintsha, izimo ezishisayo, nezimfuneko zokuphendula.Ibhalansi yokuklama efanelekile incike kuhlelo lokusebenza oluthile nendawo yokusebenza.

Izinselele kanye Neziqondiso Zocwaningo Lwesikhathi esizayo

Nakuba i-hysteresis ithuthukisa ukuziphatha kwesistimu, ingase futhi idale izinselele zokuklama njengoba amadivayisi aba mancane futhi asebenza ngesivinini esiphezulu.

Izinselelo zamanje ezihlotshaniswa ne-hysteresis zihlanganisa ukulahlekelwa kwamandla kumasistimu kazibuthe, ukukhiqizwa kokushisa, imiphumela yokuguga kwezinto ezibonakalayo, inkimbinkimbi yokumodela, nokulahlekelwa okukhulayo kumafrikhwensi aphezulu okusebenza.Le mikhawulo ingathinta ukusebenza kahle okuphelele, ukwethembeka, nokusebenza kwesistimu yesikhathi eside.

Ucwaningo oluqhubekayo luyaqhubeka nokuhlola izinto ezisetshenziswa kazibuthe ezilahlekelwa kancane, amasu okuthuthukisa asiza i-AI, ubuchwepheshe bememori ye-spitronic, izindlela zokulawula i-hysteresis eguquguqukayo, kanye nezinhlelo ezithuthukisiwe ze-semiconductor.Lezi ntuthuko zihlose ukuthuthukisa ukusebenza kahle, ukunciphisa ukulahlekelwa, nokusekela ukuziphatha kwesistimu okuhlakaniphe kakhulu.

Izinhlelo ze-elekthronikhi zesikhathi esizayo zingase zisebenzise izindlela eziguquguqukayo ze-hysteresis ezilungisa ngokuzenzakalelayo indlela yokusebenza ngokuvumelana nezimo ezishintshayo.Njengoba amadivaysi eqhubeka nokuthuthuka ngesivinini nobunkimbinkimbi, ukulawulwa kwe-hysteresis okusebenzayo kuzohlala kuwukucatshangelwa okubalulekile ekwakhiweni kwesistimu ye-elekthronikhi.

Isiphetho

I-Hysteresis isiza amasistimu kagesi ukuthi asebenze ngokwethembeka ngokuthuthukisa ukuzinza nokunciphisa ukuziphatha okungafuneki kokushintsha.Isetshenziswa kakhulu ezintweni kazibuthe, kumadivayisi we-semiconductor, amasistimu okulawula, namandla kagesi lapho izimo zokusebenza zishintsha njalo.Nakuba ingethula ukulahlekelwa kwamandla kwezinye izinhlelo zokusebenza, ukwakheka okufanele kwe-hysteresis kungathuthukisa ukusebenza kahle nokusebenza kwesikhathi eside.Ukuqonda i-hysteresis kuvumela izinqumo ezingcono ekwakhiweni kwesekethe kanye nokwenza kahle kwesistimu.
