Ezweni elisheshayo lobuchwepheshe besimanje, umqondo wemoduli udlala indima ebalulekile nebalulekile ekusebenzeni kwamadivayisi nezinhlelo ezahlukahlukene.Ama-modulatorsyizingxenye ezibalulekile ezisetshenziselwa ukuguqula kanye nokuphatha amasignali ezinhlobonhlobo zezinhlelo zokusebenza ezihlanganisa ezokuxhumana, ukusakaza kanye nokudluliswa kwedatha. Njengoba ubuchwepheshe buqhubeka buthuthuka futhi buthuthuka, ukubaluleka kwamamoduli ekusizeni ukuxhumana okuphumelelayo nokuphumelelayo akunakugcizelelwa.
Kogesi kanye nezokuxhumana, imoduli iyidivayisi noma isekethe enesibopho sokufaka ikhodi kusignali yenkampani yenethiwekhi ukuze idluliselwe. Iguqula imininingwane isuke esimweni sayo sokuqala iyenze ifomethi efanelekile ukuthi idluliselwe endaweni ethile. Le nqubo ibalulekile ekuqinisekiseni ukuthi ulwazi luyadluliswa futhi lwamukelwe ngempumelelo lapho luyiwa khona.
Enye yezinhlelo zokusebenza ezibalulekile zamamoduli ezokuxhumana, lapho zisetshenziselwa ukudlulisa izwi, idatha kanye namasiginali wevidiyo ngamanethiwekhi ahlukahlukene okuxhumana. Ezinhlelweni zokuxhumana zedijithali, amamoduli asetshenziswa ukuguqula idatha yedijithali ibe amasiginali e-analogi angase adluliselwe esiteshini sezokuxhumana se-analog. Le nqubo ivumela ukudluliswa okuphumelelayo kolwazi lwedijithali phezu kwengqalasizinda ye-analog ekhona, ivumela ukudluliswa kwedatha ngesivinini esikhulu nokuxhumana okuthembekile.
Ngaphezu kwalokho,ama-modulators zidlala indima ebalulekile kwezokusakaza nezokuzijabulisa, zisetshenziswa ekudluliseni amasignali kamabonakude nomsakazo. Ukusakazwa kukamabonakude, ngokwesibonelo, kuncike kumamoduli ukuthi aguqule amasiginali omsindo nevidiyo abe yifomethi engasakazwa ngamaza omsakazo noma ngamanethiwekhi ekhebula nesethelayithi. Ngokufanayo, ukusakazwa komsakazo kusebenzisa ama-modulators ukufaka amasignali omsindo kumagagasi enkampani yenethiwekhi ukuze adluliselwe kubamukeli.
Ngaphezu kokuxhumana ngocingo nokusakaza, amamoduli nawo abalulekile emkhakheni wokudluliswa kwedatha kanye nokuxhumana. Kumanethiwekhi ekhompyutha, amamoduli asetshenziselwa ukuguqula idatha yedijithali ibe amasiginali kagesi noma optical ukuze idluliselwe eziteshini zokuxhumana ezinezintambo noma ezingenantambo. Lokhu kuvumela ukushintshana kolwazi okungenazihibe phakathi kwamadivayisi axhunyiwe namasistimu, okusiza ukusebenza kahle kwamanethiwekhi edatha esimanje.
Intuthuko kubuchwepheshe bemoduli nayo iholele ekwakhiweni kwezinhlelo eziyinkimbinkimbi zokumodulator ezingathuthukisa ngempumelelo ukudluliswa kwesignali nokwamukela. Ubuchwepheshe obufana ne-amplitude modulation (AM), i-frequency modulation (FM), kanye ne-phase modulation (PM) buvame ukusetshenziswa ukuze kuzuzwe ukuxhumana okusebenzayo nokuthembekile. Lezi zinhlelo zokuguquguquka ziyakwazi ukufaka ikhodi kusignali yenkampani yenethiwekhi ngokunemba okuphezulu futhi zivumele isignali ukuthi idluliselwe ebangeni elide ngaphandle kokulahlekelwa okukhulu noma ukuwohloka.
Njengoba isidingo sokuxhumana ngesivinini esikhulu nokudluliswa kwedatha siqhubeka sikhula, indima yamamoduli kubuchwepheshe besimanje isalokhu ibalulekile. Ukuthuthukiswa kobuchwepheshe bemoduli ethuthukisiwe kuvule indlela yamakhono okuxhumana athuthukisiwe ukuze kudluliswe ngaphandle komthungo amasignali ezwi, idatha kanye nevidiyo ngamanethiwekhi ahlukene okuxhumana.
Ngokufigqiwe,ama-modulatorsziyingxenye ebalulekile yobuchwepheshe besimanje futhi zidlala indima ebalulekile ekudluliselweni kolwazi ngendlela ephumelelayo eziteshini ezahlukene zokuxhumana. Kusukela kwezokuxhumana kanye nokusakaza kuye ekudluliselweni kwedatha kanye nokuxhumana kwenethiwekhi, amamodulators ahamba phambili ekunikezeni amandla ukuxhumana okuthembekile nokuphumelelayo. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukubaluleka kwamamoduli ekusizeni ukuxhumana okungenazihibe kanye nokuxhumana kuzoqhubeka nokukhula.
