Ukuba ujonge indlela egqibeleleyo yokuphucula i-elektroniki ungafuna ukuqwalasela aityhubhu eyodwa yokumelana.Ezi ngokuqhelekileyo zisetyenziswa kuvavanyo lwesekethe kunye noyilo.Zingasetyenziselwa izicelo ezininzi ezahlukeneyo ezinje, amandla, okwangoku, amandla ombane, ukuxhathisa, ukuvuza kwangoku kunye nabanye.Xa ukhangela ezi ityhubhu kufuneka uqinisekise ukuba ufumana eyona ifanelekileyo kwisicelo sakho.Kukho iintlobo ezininzi ezahlukeneyo, kuquka;bipolar, pentode, triode njalo njalo.
Isizathu sokuba ityhubhu ye-bipolar ithandwa kakhulu kukuba kulula ukuseta kunye nokusetyenziswa kwe-electronics.Oku kungenxa yokuba abafuni naluphi na uhlobo lwabaqhubi bangaphandle okanye imathiriyeli ukugqiba isekethe.Endaweni yoko, zingabaqhubi abalula abazoba kwaye baguqule amandla kumanqanaba abo ombane ahlukeneyo.Ke nokuba awunawo amava amaninzi ngezinto zombane okanye awuyazi into oyenzayo, kulula ukuseta oku.Uqhagamshela nje iitheminali zegalelo kwiziphumo ezihambelanayo.
Ukuba ujonge ukuguqula umlinganiso wamandla aphezulu ube yimilinganiselo emincinci, ke ityhubhu yepentode iya kukunika eyona ndlela ilungileyo.Ziyenye yezona tyhubhu eziqhelekileyo zokulinganisa amandla aphezulu kuba ziza kwiindidi ezinkulu zobukhulu obahlukeneyo.Inzuzo enkulu kwezi ityhubhu kukuba zisebenza ngendlela emangalisayo ekuguquleni umbane ube ngamandla oomatshini.Abafuni naluphi na uhlobo lwemicu okanye ezinye izinto kwaye oku kwenza kube lula kakhulu ukuzifaka.Isenokufakwa kwakhona ukusuka phezulu ukuya ezantsi olu khetho ukuba awukhathali ukuba ugqobhoze imingxuma ethile.
Esinye sezizathu zokuba iityhubhu zepentode zisetyenziswa rhoqoityhubhu eyodwa yokumelanas kungenxa yokuba zikhawuleza kakhulu kwaye zichanekile.Bayakwazi ukwenza umsebenzi wenziwe ngokukhawuleza kunalo naluphi na uhlobo oluqhelekileyo lwetyhubhu.Bayakwazi nokuqhuba okupholileyo kakhulu kuba icandelo labo lokupholisa fan libekwe kwisiseko sesixhobo ngokwaso esipholisa amacandelo ngempumelelo ngakumbi.Olunye uncedo kwezi ityhubhu kukuba zinezikhonkwane ezincinci zokugqwetha nto leyo ethetha ukuba zivakala kakuhle nangona inqanaba lomqondiso lingekho phezulu njengoko linokuba njalo.
Ukuba ujonge ukusebenzisa ityhubhu kwiamplifier okanye esinye isixhobo sombane esinamandla aphezulu ke kubalulekile ukuba wazi kakuhle ukuba yintoni na ojongene nayo.Kukho iintlobo ngeentlobo zeetyhubhu ezibandakanya i-bipolar, i-pentode kunye nokutshintsha.Kuya kufuneka uhlale ukhetha echanekileyo kwisicelo esicetywayo ke qiniseka ukwenza uphando lwakho.Ngale ndlela awuyi kuba nexhala malunga nokonakalisa nawaphi na amacandelo xa usebenzisa uhlobo olungalunganga lwetyhubhu.
Xa ujonge ukuthenga aityhubhu eyodwa yokumelanakwiprojekthi yakho, qiniseka ukuba ubuza umthengisi ukuba loluphi uhlobo lwetyhubhu oluya kulufanelekela isicelo.Baya kuba nako ukukunika umbono olungileyo ngokusekelwe kwiimfuno zakho ngokunjalo nangokusekwe kwinto ethengwe ngabanye kutshanje.Oku kuya kunceda ukuqinisekisa ukuba ufumana imveliso efanelekileyo kwiimfuno zakho.Qiniseka ukuba ufumana lonke ulwazi oludingayo phambi kokuba uthenge nakuphi na ukuze ube nakho ukwenza isigqibo esinolwazi malunga nokuthenga.
