IIsikhulisi sesignali yeselulaiyisisetshenziswa esikhethekile, esingaxazulula inkinga abantu abaningi abavame ukuhlangana nayo lapho besebenzisa omakhalekhukhwini - isignali ebuthakathaka kanye nokuphazamiseka.Ngakho-ke, ama-amplifiers amasignali omakhalekhukhwini aya ngokuya evame kakhulu empilweni yesimanje.Izinzuzo zayo zibonakala ngokuyinhloko kulezi zici ezilandelayo.
Okokuqala, i-amplifier yesiginali yeselula ingaxazulula inkinga yesignali ebuthakathaka kanye nokuphazamiseka.Ezindaweni ezinezixuku eziminyene noma ezibuthakaukusabalala kwesignali, njengezakhiwo eziphakeme, izindawo zezintaba, imizila ehamba ngaphansi, nezinye izindawo zomphakathi, izimpawu zocingo zingase ziphazamiseke noma zingakwazi ukuxhunywa.Ukusetshenziswa kwezikhulisamsindo zesignali Yefoni Ephathwayo kungathuthukisa ngempumelelo ukuzinza nokwamukela amasignali, futhi kuqinisekise ikhwalithi yezingcingo nokushelela kokudluliswa kwedatha.
Okwesibili, iIsikhulisi sesignali yeselulailula futhi kulula ukuyisebenzisa.Ukuze usebenzise isikhulisi sesignali Yefoni Ephathwayo, ngokuvamile udinga kuphela ukuxhuma uthi lwesikhulisi ngqo kumakhalekhukhwini.I-amplifier izosesha ngokuzenzakalelayo futhi ixhume amasiginali atholakalayo eduze kwayo, izuze ukukhuliswa kwesignali nokudlulisa.Ngesikhathi esifanayo, isikhulisi sesiginali yeselula sinomsebenzi wokukhetha amasignali weziteshi eziningi, ongashintsha ngokuzenzakalelayo ngaphansi kwamasignali enethiwekhi ahlukene ukuqinisekisa ukuqhubeka kokudluliswa kwesignali.
Ngaphezu kwalokho, ama-amplifiers amasignali eselula angakwazi futhi ukwengeza ezinye izici eziphezulu kumakhalekhukhwini abajwayelekile, njengokuma kwesathelayithi, ukuthumela imiyalezo esheshayo, ukuphequlula iwebhu, njll. Ngemva kokusetshenziswa kwesikhulisi sesignali sikamakhalekhukhwini, ikhwalithi yesiginali yeselula inesiginali. ithuthukisiwe, futhi isivinini sokuphendula sohlelo lwefoni ephathekayo nalo selushesha kakhulu.Uma usebenzisa amasistimu okuzulazula noma ezinye izinhlelo zokusebenza zeselula emadolobheni, ukuzinza kwesignali kuyaqinisekiswa ukugwema ukungingiza noma ukungakwazi ukusebenzisa.
Ngokuvamile, inzuzo eyinhloko yeIsikhulisi sesignali yeselulaukuthuthukisa ikhono lokuxhumana nokusebenzisa ulwazi lwamaselula.Ukusebenzisa ama-amplifiers kungagwema izinkinga ezivamile ezifana nokuphazamiseka komugqa namasignali angazinzile.Uma usebenzisa umakhalekhukhwini ukuxhumana, ukuphequlula, ukubeka indawo, ukudlala, neminye imisebenzi, izikhulisi zihlinzeka ngezimo zenethiwekhi ezizinzile nezibushelelezi zocingo, zisisiza ukuthi sijabulele kangcono ukunethezeka okulethwa ubuchwepheshe.
Ngamafuphi,Isikhulisi sesignali yeselula, njengendlela yobuchwepheshe yokwandisa isidingo, isetshenziswe kabanzi futhi yanda ekuphileni kwanamuhla.Izinzuzo zayo ikakhulu zilele ekuthuthukiseni ikhwalithi yokuxhumana, ukusebenza okulula, nokuthuthukisa ukusebenza komakhalekhukhwini.Ngokuthuthuka okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe, izikhulisi zesignali zikamakhalekhukhwini zizoba idivayisi ebalulekile kanye nezindlela zobuchwepheshe embonini yomakhalekhukhwini, zilethe ulwazi olucebile futhi olulula empilweni yethu yokuxhumana.
