Izandisi zesandisi eziphathwayoazinabungozi ngokungqalileyo. Zizixhobo zombane ezenzelwe ukomeleza iisignali ezihambayo, eziquka i-eriyali yangaphandle, iamplifier, kunye ne-eriyali yangaphakathi edityaniswe ngeentambo. Injongo yezi zixhobo kukufaka imiqondiso ebuthathaka kwaye iyandise ukuze ibonelele ngomgangatho ongcono wonxibelelwano oluphathwayo kunye nokugubungela umqondiso.
Nangona kunjalo, kukho amanqaku amaninzi ekufuneka uwaqwalasele xa usebenzisa i-amplifiers yesignali yeselula:
Okusemthethweni: Xa usebenzisa iisandisi sesandisi esiphathwayo, kufuneka uqinisekise ukuba isemthethweni kwaye ihambelana nemimiselo yendawo. Iindawo ezithile zinokuba nezithintelo okanye izithintelo ekusebenziseni i-amplifiers kwiibhendi ezithile zamaza, njengoko zinokuphazamisana nokusebenza okuqhelekileyo kwezinye izixhobo ezingenazingcingo okanye izitishi ezisisiseko.
Ufakelo olungafanelekanga kunye nokusetyenziswa: Ufakelo olungafanelekanga okanye ukusetyenziswa kakubi kwe-amplifier yesignali kunokukhokelela ekuphazamiseni kunye nemiba. Umzekelo, ukuba ubude bekhebula phakathi kwee-eriyali zangaphakathi nangaphandle zinde kakhulu okanye ukuba i-wiring ayifanelekanga, inokwazisa ukulahleka komqondiso okanye iingxaki zempendulo.
Imitha yombane:Izandisi zesandisi eziphathwayozifuna unikezelo lwamandla, nto leyo ethetha ukuba bavelisa inqanaba elithile lemitha ye-electromagnetic radiation. Nangona kunjalo, xa kuthelekiswa neefowuni eziphathwayo okanye ezinye izixhobo zonxibelelwano ezingenazingcingo, inqanaba lemitha yeamplifiers lihlala lisezantsi kuba zihlala ziyilelwe ukusetyenziswa kwangaphakathi endaweni yokuba kufutshane nomzimba womntu. Nangona kunjalo, ukuba unovelwano kwimitha ye-electromagnetic okanye unenkxalabo yezempilo, unokuthatha amanyathelo okhuseleko afanelekileyo njengokuhlala kude neamplifier okanye ukukhetha izixhobo ezinemitha esezantsi.
Ukuphazamiseka koMqondiso: Ngelixa injongo yeii-amplifiers zesignali ephathwayokukubonelela ngemiqondiso eyomeleleyo, ufakelo olungafanelekanga okanye ukusetyenziswa kunokwazisa uphazamiseko lwesiginali. Umzekelo, ukuba i-amplifier ibamba kwaye ikhulise imiqondiso ephazamisayo evela kwizixhobo ezikufutshane, inokubangela ukuhla komgangatho wonxibelelwano okanye ukuphazamiseka.
Ngamafutshane, ii-amplifiers ezifunyenwe ngokusemthethweni kwaye zifakwe ngokufanelekileyo azinabungozi ngqo. Nangona kunjalo, kubalulekile ukuthobela imithetho yendawo, ulandele iingcebiso kunye nezikhokelo zomenzi, kwaye uqinisekise ukufakela kunye nokusetyenziswa okufanelekileyo. Ukuba unayo nayiphi na inkxalabo okanye imibuzo, kungcono udibane neengcali okanye abasemagunyeni abafanelekileyo ukufumana iingcebiso ezichanekileyo kunye nesikhokelo.
