Ngokuthuthuka okusheshayo kobuchwepheshe besimanje bezokuxhumana, omakhalekhukhwini sebeyithuluzi elibalulekile ezimpilweni zabantu.Nokho, naphezu kwentuthuko kwezobuchwepheshe bezokuxhumana, sisahlangabezana nezinkinga zokungatholakali kahle kwamasignali ezindaweni ezithile.Ikakhulukazi emhubheni, ngenxa yemikhawulo yendawo kanye nezakhiwo, isignali yeselula ivame ukuba buthaka noma ilahleke ngokuphelele.Kulokhu, ukusetshenziswaAma-amplifiers amasignali eselulakungaba ekahleisisombululoenkingeni.
Isikhulisi sesignali yeselula iyisisetshenziswa esiklanyelwe ngokukhethekile ukuthuthukisa ukumbozwa kwesiginali kanye nekhwalithi yesiginali.Ithola amasiginali abuthakathaka kumakhalekhukhwini, bese iwakhulisa futhi iwaqinise ukuze ithumele kabusha amasignali esiteshini sesisekelo esingumakhalekhukhwini.Ngale ndlela, isignali ingamboza indawo ebanzi futhi igcine uxhumano oluzinzile.Kulabo abavame ukusebenza emhubheni noma abadlulayo, isikhulisi sesignali yocingo lweselula ngokungangabazeki siyisinqumo esingcono kakhulu sokuxazulula izinkinga zokuxhumana.
Ama-amplifiers amasignali eselula yesimanje asebenzisa ubuchwepheshe obuthuthukisiwe ukuze anqobe ubunkimbinkimbi bendawo yomhubhe.Banenzuzo ephezulu, isibalo esiphansi somsindo, kanye nebanga elibanzi lefrikhwensi, elingajwayelana nezidingo zamabhendi efrikhwensi yesiginali.Ukwengeza, amanye ama-amplifiers amasignali eselula nawo anomsebenzi wokulawula okuzenzakalelayo, ongalungisa ngobuhlakani inzuzo namandla ukuze kuqinisekiswe ukuzinza nokuvikeleka kokudluliswa kwesignali.
Ama-amplifiers amasignali eselula yesimanje asebenzisa ubuchwepheshe obuseqophelweni eliphezulu ukunqoba inkimbinkimbi yeimvelo yomhubhe.Banayoinzuzo ephezulu, isibalo somsindo ophansi, kanye nebanga elibanzi lefrikhwensi, elingajwayelana nezidingo zamabhendi efrikhwensi yesignali ehlukene.Ukwengeza, amanye ama-amplifiers amasignali eselula nawo anomsebenzi wokulawula okuzenzakalelayo, ongalungisa ngobuhlakani inzuzo namandla ukuze kuqinisekiswe ukuzinza nokuvikeleka kokudluliswa kwesignali.
Ukusebenzisa i-amplifier yesignali yeselula akukwazi ukuxazulula inkinga yomhubhe kuphelaukusabalala kwesignali, kodwa futhi uthuthukise ikhwalithi yekholi kanye nesivinini sokudluliswa kwedatha.Ezimweni ezinekhwalithi yesignali ephansi, izingcingo zamaselula zivame ukuhlangana nezinkinga ezifana nomsindo ongacacile nokulahlekelwa izwi.Ngama-amplifiers amasignali omakhalekhukhwini, lezi zinkinga zizoncishiswa kakhulu noma zinyamalale.Ukwengeza, kulabo abathembele ekuxhumekeni kwe-inthanethi okusheshayo, isikhulisi sesignali yocingo lweselula singanikeza isivinini sokudlulisa idatha esisheshayo kanye noxhumano lwenethiwekhi oluzinzile, ngaleyo ndlela kuthuthukiswe ukusebenza kahle komsebenzi kanye nezinga lempilo.
Kunezinto ezimbalwa okufanele zicatshangelwe lapho kukhethwa izikhulisi zamasignali zikamakhalekhukhwini.Okokuqala, kuyadingeka ukunquma usayizi nokuma komhubhe ukuze ukhethe uhlobo olufanele lwe-amplifier yesiginali namandla.Okwesibili, ucabangela umehluko phakathi kwama-opharetha abahlukene namabhendi efrikhwensi yesignali, qinisekisa ukuthi isikhulisi sesignali Sefoni Ephathwayo singahambisana nohlelo lwenethiwekhi oyisebenzisayo.Ukwengeza, kufanele futhi kuqashelwe ukufakwa kanye nokusetshenziswa kwezikhulisi zesignali Yefoni Ephathwayo ukuze kuqinisekiswe ukusebenza ngempumelelo kwezisetshenziswa kanye nokwandisa ukusebenza kahle.
Kafushane, indaba yokumbozwa kwesignali yomhubhe iyinkinga evamile kulabo abavame ukusebenza noma abadlula emhubheni.Ngesikhathi esifanayo, i-amplifier yesignali yocingo lweselula, njengedivayisi esebenzisa ubuchwepheshe obuthuthukisiwe ukuxazulula izinkinga zesignali, ingahlinzeka ngoxhumano lwesignali ezinzile kanye nolwazi lokuxhumana lwekhwalithi ephezulu.Khetha isikhulisi sesignali yeselula esilungele izidingo zakhoxazulula izinkinga zakho zesignalifuthi uthuthukise impilo yakho nokusebenza kahle.
