Ngiyakuthanda ukudala okuqukethwe kwamahhala okugcwele izeluleko zabafundi bami, wena. Angilwamukeli uxhaso olukhokhelwayo, umbono wami owami, kepha uma uthola izincomo zami zilusizo futhi ugcina uthenga okuthile okuthandayo ngesinye sezixhumanisi zami, bengingathola ikhomishini ngaphandle kwezindleko ezengeziwe kuwe.

I-cathode ray oscilloscope noma i-oscillograph iyinsimbi kagesi esetshenziselwa ukuguqula amasiginali kagesi abe amasignali abukwayo. Le nsimbi ilinganisa futhi ihlaziye ifomu lokuphakama nezinye izinto ezenzeka ngogesi. Futhi kuyisiqeshana se-XY esakha isignali yokufaka ngokuqhathanisa nenye isignali noma isikhathi. I-cathode ray oscilloscope ifana neshubhu lokukhipha; kukuvumela ukuthi ubone ukushintsha kwezimpawu zikagesi ngokuhamba kwesikhathi. Lokhu kusetshenziselwa ukuhlaziya futhi bala imvamisa, i-amplitude, ukuhlanekezela, nezinye izinto ezihluka-hlukanisa isikhathi kusuka kumvamisa ophansi kuya kumvamisa yomsakazo. Iphinde isetshenziswe ocwaningweni lwama-acoustic nasekukhiqizeni ithelevishini.
Kulokhu okuthunyelwe sizomboza:
Izakhi Eziyinhloko
Kuthuthukiswe yisazi sefilosofi saseJalimane uFerdinand Braun i-cathode ray oscilloscope iqukethe izingxenye ezine eziyinhloko; okuyishubhu le-cathode ray, isibhamu se-electron, uhlelo lokuphambuka, nesikrini se-fluorescent.
Ukusebenza Isimiso
Isibhamu se-electron sakha ugongolo oluncane lwama-electron, futhi inhlayiya idlula ngegridi yokulawula. Igridi yokulawula ilawula ukuqina kwe-electron ngaphakathi kweshubhu elingenalutho. Indawo emfushane ikhiqizwa esikrinini uma igridi yokulawula inamandla aphezulu amabi, futhi amandla amancane aphansi akhiqiza indawo ekhanyayo kugridi yokulawula. Ngakho-ke, amandla okukhanya alawulwa amandla amabi wegridi yokulawula. Ngemuva kwalokho ama-electron asheshiswa ngama-anode anamandla amahle kakhulu. Iguqula ugongolo lwe-electron endaweni ethile esikrinini. Ngemuva kokuhamba kusuka ku-anode, lolu gongolo lwe-electron lwaphambukiswa ngamapuleti ahlanekezelayo. Ipuleti elihlanekezelayo lihlala lingenamandla amakhulu, futhi ugongolo lwe-electron lukhiqiza indawo esikhungweni sesikrini. Ugongolo lwe-electron lugxila kokuya phezulu uma amandla kagesi esetshenziswa kupuleti eliqonde mpo lokuphambuka. Ugongolo lwe-electron luzophambuka lubheke phezulu ngokusebenzisa i-voltage epuletini evundlile ehlulwayo.
Izicelo
I-cathode ray oscilloscope isetshenziselwa ukudlulisa kanye neyunithi yokwamukela ithelevishini. Ibuye isetshenziselwe ukuguqula imizwa kagesi ehambelana nokushaya kwenhliziyo kube amasiginali abonakalayo. Ukuthola izindiza zezitha, kusetshenziswa futhi ngaphakathi kohlelo lwe-radar nangaphakathi kwelabhorethri ngezinjongo zemfundo.
Ithelevishini
I-cathode-ray oscilloscope isebenza njengethubhu yesithombe ngaphakathi kwethelevishini. Amasiginali wevidiyo athunyelwe asuka kusidlulisi sethelevishini asetshenziselwa ukubheka amapuleti ahlanekezela ngaphakathi kwe-cathode ray oscilloscope. Ngemuva kwalokho i-electron beam ishaya isikrini, futhi isikrini siqukethe uhlu lwamabala amancane. Indawo ngayinye yakhiwe ngamachashazi amathathu e-phosphor, amele imibala eyinhloko, obomvu, oluhlaza okotshani nokuhlaza okwesibhakabhaka. Amachashazi e-Phosphor ayakhanya njengoba ehlaselwa ngogongolo lwe-electron. Uma umsebe we-electron uyisigameko esingaphezu kweyodwa i-phosphor endaweni ethile, khona-ke umbala wesibili uyabonakala. Inhlanganisela yemibala emithathu eyinhloko ngokwesilinganiso esifanele ingaveza isithombe esinemibala esibukweni. Uma sibuka phambi kwethelevishini, indawo ene-phosphor ihamba ngephethini efana nokuhamba kwamehlo abantu, ngesikhathi kufundwa umbhalo. Kepha le nqubo yenzeka ngesivinini esisheshayo kangangokuba amehlo ethu abona isithombe njalo esikrinini sonke.
Ezemfundo Nocwaningo
Esifundweni esiphakeme, i-cathode-ray oscilloscope isetshenziselwa ukuhlangana. Isetshenziselwa ukunquma amafomu amagagasi, ukuhlaziya izakhiwo zayo. Ubuningi obuhlukahluka besikhathi bukalwa kusukela kumvamisa ophansi kuya kubukhulu njenge-radiofrequency. Kungenzeka futhi linganisa umehluko ongaba khona ku-voltmeter. Enye inzuzo yale cathode-ray oscilloscope ukuthi ikwazi ukuhlela amasiginali ngokucacile nangokunembile ukukala izikhathi ezimfushane zesikhathi. Isibalo seLissajous singakhiwa kalula ngosizo lwale nsimbi. Ngalezi zizathu, kusetshenziswa i-oscilloscope kabanzi emikhakheni yokufunda nokutadisha ephakeme.
Ubuchwepheshe beRadar
I-Radar iyithuluzi elenza ngogesi elethula imininingwane yezindiza zesitha kumqhubi we-radar noma kumshayeli wendiza. Uhlelo lwe-radar ludlulisa izinhlamvu noma amagagasi emisebe kagesi aqhubekayo. Ingxenye encane yalokho kugagadla emuva kwamagagasi futhi ibuyele ohlelweni lwe-radar.
Isiphetho
I-Cathode ray oscilloscope noma i-oscillograph yinto esungulwe kabusha. Kwavula indlela yokwenza ithelevishini yeCRT, eyayiyinto enhle kakhulu esungulwe isintu. Kusuka entweni yaselebhu kuya engxenyeni ebalulekile yomhlaba we-elekthronikhi, kukhombisa njengokukhalipha komuntu.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
