Isikhulisi sesignali yeselulayisisetshenziswa esisetshenziswa ukuthuthukisa isignali yefoni Ephathwayo. Iwusizo kakhulu ezindaweni eziningi, ikakhulukazi ezindaweni ezinezimpawu ezibuthakathaka noma amakhona afile. Kulesi sihloko, sizoxoxa ngomgomo wokusebenza we-Mobile phone amplifier ngokujulile, futhi sethule ukuthi isebenza kanjani ngokuningiliziwe.
Ake sibheke izingxenye zesikhulisi sesignali yeselula. Isikhulisi sesignali seselula esijwayelekile sakhiwe ikakhulukazi uthi lwangaphandle, i-antenna yasendlini, iamplifier nolayini wokudlulisa. Ama-antenna angaphandle asetshenziselwa ukwamukela amasignali abuthakathaka kusukaiziteshi eziyisisekelo zomakhalekhukhwinifuthi uwadlulisele kuma-amplifiers. Ngemva kokuthola isignali ebuthakathaka, i-amplifier icubungula i-amplification ngaphambi kokuyidlulisela ku-antenna yasendlini. I-antenna yasendlini ithumela isignali ekhulisiwe kumaselula azungezile, ngaleyo ndlela ithuthukise ikhono lawo lokwamukela amasignali.
Okulandelayo, funda kabanzi mayelana nesimiso sokusebenza se-Amplifaya yesiginali yomakhalekhukhwini. Okokuqala, lapho iselula ithola isignali evela esiteshini esiyisisekelo, isignali iba buthaka kakhulu ngenxa yezizathu ezithile, njengokungabi kude nesiteshi noma ukuphazamiseka kwendawo ezungezile. Kuleli qophelo, ifoni ingase ingasebenzi kahle noma ikhwalithi yocingo ingase ibe mbi kakhulu. Umsebenzi wesikhulisi sesignali Yefoni Ephathwayo ukuthola lezi zimpawu ezibuthakathaka futhi uzikhulise, ukuze uvale ukulahleka kwamasignali futhi unike amandla amasignali ukuthi adluliselwe ngempumelelo endlini.
Isikhulisi sesignali Yefoni Ephathwayo sithola amasignali abuthakathaka ngothi lwangaphandle, bese luwathumela kusikhulisi ukuze akhulise. I-amplifier isebenzisa izingxenye ezithile ze-elekthronikhi namasekhethi ukuze ikhulise isignali ebuthakathaka eyamukelwe ibe sezingeni elifanele. Isignali ekhulisiwe ibe isidluliselwa ku-antenna yasendlini ngomugqa wokudlulisela. I-antenna yasendlini isakaza isignali ekhulisiwe kumaselula azungezile, okubenza bakwazi ukuthola isignali ethuthukisiwe.
Kuyaqapheleka ukuthi isikhulisi sesignali yocingo lweselula ngeke sidale amasiginali amasha, kodwa sikhulise futhi sidlulise izimpawu zokuqala ezibuthakathaka. I-amplifier izokhulisa futhi icubungule isignali eyamukelwe ngokusekelwe kwikhwalithi yayo ukuze kuqinisekiswe ukuthi isignali ihlala izinzile ngesikhathi sokudlulisa.
Ngaphezu kwalokho, ama-amplifiers amasignali efoni kamakhalekhukhwini avame ukusebenzisa eminye imisebenzi eyengeziwe ukuze athuthukise ukusebenza kwawo. Isibonelo, ezinye izikhulisi zesignali Yefoni Ephathwayo zinomsebenzi wokulawula inzuzo ezenzakalelayo, engalungisa ngokuzenzakalelayo ukukhulisa ngokuya ngamandla amasiginali azungezile ukuze kuqinisekiswe ikhwalithi yesiginali ehamba phambili. Ukwengeza, ezinye izikhulisi zamasignali ezithuthukisiwe zikamakhalekhukhwini zingase futhi zisekele amabhendi amafrikhwensi amaningi ngesikhathi esisodwa, ezifanele izidingo zokukhulisa isignali zama-opharetha abehlukene noma amaza ahlukene.
Ukufingqa, isikhulisi sesiginali yeselula iyisisetshenziswa esithuthukisa ikhwalithi yesiginali Yefoni Ephathwayo ngokwamukela nokukhulisa amasignali abuthakathaka. Yakhiwe ngothi lwangaphandle, i-antenna yasendlini, i-amplifier kanye nolayini wokudlulisa, kanye ne-ukuthuthukiswa kwesignalikwenziwa ngezimiso ezithile zokusebenza. Lapho ukhetha futhi usebenzisa izikhulisamsindo zesignali Yefoni Ephathwayo, abasebenzisi kudingeka benze ukukhetha okufanele ngokwezidingo zabo kanye nendawo yesiginali.
