Ama-amplifiers amasignali eselulangokwabo abanalo ukulimala okuqondile. Amadivayisi kagesi aklanyelwe ukuthuthukisa amasignali eselula, ngokuvamile ahlanganisa uthi lwangaphandle, isikhulisi, nothi lwasendlini oluxhunywe ngamakhebuli. Inhloso yalawa madivaysi ukubamba amasignali abuthakathaka futhi awakhulise ukuze anikeze ikhwalithi yokuxhumana yeselula engcono kanye nokufakwa kwesignali.
Nokho, kunamaphuzu amaningana okufanele uwacabangele lapho usebenzisa izikhulisamandla zesignali yeselula:
Okusemthethweni: Uma usebenzisa iisandisi sesignali yeselula, udinga ukuqinisekisa ukuthi isemthethweni futhi ihambisana nemithetho yendawo. Ezinye izindawo zingase zibe nemikhawulo noma zinqatshelwe ukusetshenziswa kwezikhulisa-zwi kumabhendi athile efrikhwensi, njengoba zingaphazamisa ukusebenza okuvamile kwamanye amadivaysi angenawaya noma iziteshi eziyisisekelo.
Ukufakwa nokusetshenziswa okungalungile: Ukufakwa okungalungile noma ukusetshenziswa okungalungile kwe-amplifier yesignali kungaholela ekuphazamiseni nasezinkingeni. Isibonelo, uma ubude bekhebula phakathi kwezinti zasendlini nezangaphandle bude kakhulu noma uma izintambo zingalungile, zingase zethule ukulahlekelwa kwesignali noma izinkinga zempendulo.
Imisebe ye-electromagnetic:Ama-amplifiers amasignali eselulazidinga ukunikezwa kwamandla, okusho ukuthi zikhiqiza izinga elithile lemisebe kagesi. Kodwa-ke, uma kuqhathaniswa nomakhalekhukhwini noma ezinye izisetshenziswa zokuxhumana ezingenazintambo, izinga lemisebe yezikhulisa-msindo ngokuvamile liphansi ngoba ngokuvamile zenzelwe ukusetshenziswa endlini kunokuba seduze nomzimba womuntu. Noma kunjalo, uma uzwela emisebeni kazibuthe kagesi noma unezinkinga zempilo, ungathatha izinyathelo zokuphepha ezifanele njengokuhlala kude ne-amplifier noma ukukhetha amadivaysi anemisebe ephansi.
Ukuphazamiseka kwesignali: Ngenkathi inhloso yeama-amplifiers amasignali eselulaukuhlinzeka ngamasignali anamandla, ukufakwa okungafanele noma ukusetshenziswa kungase kwethule ukuphazamiseka kwesignali. Isibonelo, uma i-amplifier ithwebula futhi ikhulise amasignali aphazamisayo kusukela kumadivayisi aseduze, kungase kubangele ukwehla kwekhwalithi yokuxhumana noma ukuphazamiseka.
Kafushane, izikhulisi zesignali yeselula ezitholwe ngokusemthethweni zafakwa kahle ngokuvamile azinawo umonakalo oqondile. Nokho, kubalulekile ukuthobela imithetho yendawo, ulandele izincomo nemihlahlandlela yomkhiqizi, futhi uqinisekise ukufakwa nokusetshenziswa okufanele. Uma unokuthile okukukhathazayo noma imibuzo, kungcono ukuthintana nochwepheshe noma iziphathimandla ezifanele ukuze uthole iseluleko esinembile nesiqondiso.
