Ndiyakuthanda ukudala umxholo okhululekileyo ogcwele iingcebiso kubafundi bam, wena. Andilwamkeli uxhaso oluhlawulelweyo, uluvo lwam lolwam, kodwa ukuba ufumanisa ukuba izindululo zam ziluncedo kwaye ugqibela ngokuthenga into oyithandayo ngenye yeekhonkco zam, ndingafumana ikhomishini ngaphandle kwendleko ezongezelelweyo kuwe.

I-cathode ray oscilloscope okanye i-oscillograph sisixhobo sombane esisetyenziselwa ukuguqula imiqondiso yombane ukuya kwimiqondiso ebonakalayo. Esi sixhobo silinganisa kwaye sihlalutye ukubonwa kwamaza kunye nezinye izinto zombane. Ikwayisiqwenga seXY esilungiselela isiginali yokufaka ngokuchasene nomnye umqondiso okanye ixesha. I-cathode ray oscilloscope iyafana kumbhobho wokukhupha; ikuvumela ukuba ubone utshintsho lweempawu zombane ngokuhamba kwexesha. Oku kusetyenziswa ukuhlalutya kunye Bala rhoqo, Amplitude, ukugqwetha, kunye namanye amaxesha ahluka-hlukeneyo ukusukela kumaza asezantsi ukuya kumaza oonomathotholo. Ikwasetyenziselwa kuphando lwe-acoustic kunye nemveliso yeTV.
Kule posi siza kugubungela:
Izinto eziphambili
Iphuhliswe ngu-physicist waseJamani uFerdinand Braun i-cathode ray oscilloscope inamalungu amane aphambili; Yeyiphi ityhubhu ye-cathode ray, umpu we-electron, inkqubo yokuphambuka, kunye nescreen fluorescent.
Principle Working
Umpu we-elektroni uvelisa umqadi omxinwa wee-elektroni, kwaye isuntswana lidlula kwigridi yolawulo. Igridi yolawulo ilawula ubunzulu be-electron ngaphakathi kwityhubhu yokucoca. Indawo efipheleyo iveliswa kwiscreen ukuba igridi yolawulo inokubakho okungalunganga okuphezulu, kwaye amandla amabi asezantsi avelisa indawo eqaqambileyo kwigridi yolawulo. Ke, ukukhanya kobushushu kulawulwa kukungabi namandla kwigridi yolawulo. Emva koko ii-elektroni zikhawuleziswa zii-anode ezinesakhono esiphakamileyo. Iguqula ibram ye-elektroni kwindawo ekwisikrini. Emva kokuhamba ukusuka kwi-anode, le ntsika ye-elektroni yaphambuka kwiipleyiti eziphambukayo. Ipleyiti yokuphambuka ihlala ikwiziro enokubakho, kwaye umqadi we-elektroni uvelisa indawo kwiziko lesikrini. Umqadi we-electron ugxila phezulu xa umbane usetyenziswa kwipleyiti ethe nkqo. Umqadi we-electron uya kuphambuka ngokuthe tye ngokusebenzisa i-voltage kwitheyibhile yokuphambuka ethe tyaba.
izicelo
I-cathode ray oscilloscope isetyenziselwa ukuhambisa kunye nakwiyunithi yokufumana ithelevishini. Isetyenziselwa ukuguqula iimpembelelo zombane ezihambelana nokubetha kwentliziyo kwiimpawu ezibonakalayo. Ukufumana inqwelomoya yenqwelomoya, ikwasetyenziswa ngaphakathi kwenkqubo ye-radar nangaphakathi elebhu ukulungiselela iinjongo zemfundo.
Television
I-cathode-ray oscilloscope isebenza njengetyhubhu yomfanekiso ngaphakathi kumabonwakude. Imiqondiso yevidiyo ethunyelwe kumthumeli kamabonwakude isetyenziselwa iipleyiti eziphambukayo ngaphakathi kwe-cathode ray oscilloscope. Emva koko umqadi we-elektroni ubetha kwiscreen, kwaye isikrini siqulathe uluhlu lwamabala amancinci. Indawo nganye inamachaphaza amathathu e-phosphor, amele imibala ephambili, ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka. Amachaphaza e-Phosphor ayakhanya njengoko ehlaselwa ngumqadi we-elektron. Ukuba umqadi we-electron uyisiganeko esingaphezulu kwesinye se-phosphor kwindawo ethile, umbala wesibini uyabonakala. Ukudityaniswa kwemibala emithathu ephambili kumgangatho ofanelekileyo kunokuvelisa umfanekiso onemibala kwiscreen. Xa sijonga phambi kukamabonwakude, indawo ene-phosphor ehambayo ihamba kwipateni efanayo nokuhamba kwamehlo abantu, ngexesha lokufunda isicatshulwa. Kodwa le nkqubo yenzeka ngesantya esikhawulezayo kangangokuba amehlo ethu abona umfanekiso ongagungqiyo kwiscreen sonke.
Ezemfundo noPhando
Kwisifundo esiphakamileyo, i-cathode-ray oscilloscope isetyenziselwa iseshoni. Isetyenziselwa ukumisela iifomathi, uhlalutye iipropathi zayo. Amaxesha ahluka-hlukeneyo alinganiswa ukusukela kumaza asezantsi ukuya kubukhulu njenge-radiofrequency. Kunokuba njalo linganisa umahluko onokubakho kwi-voltmeter. Olunye uncedo lwale cathode-ray oscilloscope kukuba inokuthi icwangcise imiqondiso ngokuchanekileyo nangokuchanekileyo yokulinganisa ixesha elifutshane. Umzobo kaLissajous ungacwangciswa ngokulula ngoncedo lwesi sixhobo. Ngezi zizathu, i-oscilloscope isetyenziswa ngokubanzi kumacandelo aphezulu ophando kunye nophando.
Itekhnoloji yeRadar
I-Radar sisixhobo se-elektroniki esibonisa idatha yeenqwelomoya kwi-radar okanye kumqhubi wenqwelomoya. Inkqubo ye-radar ihambisa iimpompo okanye amaza ombane aqhubekekayo ombane. Inxalenye encinci yelahleko libuyela umva ekujoliswe kulo kwaye libuyele kwinkqubo ye-radar.
isiphelo
I-Cathode ray oscilloscope okanye i-oscillograph yinto ehlaziyiweyo. Yavula indlela yokwenza umabonakude weCRT, owawungoyena ndoqo umangalisayo woluntu. Ukusuka kwinto yaselebhu ukuya kwindawo ebalulekileyo kwilizwe le-elektroniki, kubonakala njengokuqaqamba komntu.
NdinguJoost Nusselder, umseki weZixhobo zeGqirha, umthengisi womxholo, kunye notata. Ndiyathanda ukuzama izixhobo ezitsha, kwaye kunye neqela lam ndiye ndenza amanqaku ebhlog anzulu ukusukela ngo-2016 ukunceda abafundi abathembekileyo ngezixhobo kunye neengcebiso zokwenza.
