Kwihlabathi elikhawulezayo letekhnoloji yanamhlanje, umbono wemodyuli udlala indima ebalulekileyo kunye nebalulekileyo ekusebenzeni kwezixhobo ezahlukeneyo kunye neenkqubo.Iimodyulingamacandelo abalulekileyo asetyenziselwa ukuguqula kunye nokulawula imiqondiso kuluhlu olubanzi lwezicelo ezibandakanya unxibelelwano, usasazo kunye nokuhanjiswa kwedatha.Njengoko itekhnoloji iqhubela phambili kwaye iphuhlisa, ukubaluleka kweemodyuli ekuququzeleleni unxibelelwano olusebenzayo nolusebenzayo alunakugqithiswa.
Kwi-electronics kunye ne-telecommunications, imodyuli sisixhobo okanye isekethe enoxanduva lokukhowuda ulwazi kwisignali yenkampani yothutho.Ngokusisiseko iguqula ulwazi olusuka kwimo yalo yoqobo lube kwifomathi elungele ukuhanjiswa ngaphaya kwendlela ethile.Le nkqubo ibalulekile ekuqinisekiseni ukuba ulwazi ludluliselwa kwaye lwamkelwa ngokufanelekileyo kwindawo ekujoliswe kulo.
Esinye sezicelo eziphambili zeemodyuli kukunxibelelana ngomnxeba, apho zisetyenziselwa ukuhambisa ilizwi, idatha kunye nemiqondiso yevidiyo kwiinethiwekhi ezahlukeneyo zonxibelelwano.Kwiinkqubo zonxibelelwano lwedijithali, iimodyuli zisetyenziselwa ukuguqula idatha yedijithali ibe yimiqondiso ye-analog enokudluliselwa kwijelo lonxibelelwano lwe-analog.Le nkqubo ivumela ukuhanjiswa ngokufanelekileyo kolwazi lwedijithali phezu kweziseko ze-analog ezikhoyo, okwenza ukuhanjiswa kwedatha ngesantya esiphezulu kunye nonxibelelwano oluthembekileyo.
Ngaphezu koko,iimodyuli zidlala indima ebalulekileyo kusasazo nakulonwabo, zisetyenziswa ekusasazeni imiqondiso kamabonakude neyerediyo.Usasazo lukamabonwakude, umzekelo, luxhomekeke kwiimodyuli ukuguqula imiqondiso yeaudio kunye nevidiyo kwifomathi enokuhanjiswa ngamaza kanomathotholo okanye ngothungelwano lwentambo kunye nesathelayithi.Ngokukwanjalo, usasazo lukanomathotholo lusebenzisa iimodyuli ukubethelela imiqondiso yomsindo kumaza othuthi ukuze adluliselwe kubamkeli.
Ukongeza kuthungelwano kunye nosasazo, iimodyuli zikwabalulekile kwicandelo losasazo lwedatha kunye nothungelwano.Kuthungelwano lwekhompyuter, iimodyuli zisetyenziselwa ukuguqula idatha yedijithali ibe yimiqondiso yombane okanye ye-optical yokuhanjiswa kwiitshaneli zonxibelelwano ezinocingo okanye ezingenazingcingo.Oku kwenza utshintshiselwano olungenamthungo lolwazi phakathi kwezixhobo eziqhagamshelweyo kunye neenkqubo, kuququzelela ukusebenza ngokufanelekileyo kothungelwano lwedatha yanamhlanje.
Inkqubela phambili kwitekhnoloji yemodyuli ikhokelele kuphuhliso lwezikimu zokumodareyitha ezintsonkothileyo ezinokwandisa ngokufanelekileyo ukuhanjiswa nokwamkelwa komqondiso.Ubuchwephesha obufana ne-amplitude modulation (AM), i-frequency modulation (FM), kunye ne-modulation phase (PM) ngokuqhelekileyo isetyenziselwa ukuphumeza unxibelelwano olusebenzayo noluthembekileyo.Ezi zicwangciso zokumodareyitha ziyakwazi ukubethelela ulwazi kwi-signal carrier ngokuchaneka okuphezulu kwaye uvumele ukuba umqondiso udluliselwe kumgama omde ngaphandle kokulahlekelwa okukhulu okanye ukuthotywa.
Njengoko imfuno yonxibelelwano ngesantya esiphezulu kunye nokuhanjiswa kwedatha kuqhubeka nokukhula, indima yeemodyuli kubuchwephesha bale mihla ihlala ibalulekile.Uphuhliso lwetekhnoloji yemodyuli ephucukileyo ivule indlela yokuphucula izakhono zonxibelelwano ukuze zisasaze ngaphandle komthungo imiqondiso yelizwi, idatha kunye nevidiyo kuthungelwano olwahlukeneyo lonxibelelwano.
Isishwankathelo,iimodyuliziyinxalenye yethekhinoloji yale mihla kwaye zidlala indima ebalulekileyo ekuhanjisweni kolwazi ngokufanelekileyo kumajelo ohlukeneyo onxibelelwano.Ukusuka kuthungelwano ngocingo kunye nosasazo ukuya kugqithiso lwedatha kunye nothungelwano, iimodyuli zihamba phambili ekwenzeni unxibelelwano oluthembekileyo nolusebenzayo.Njengoko itekhnoloji iqhubeka nokuhambela phambili, ukubaluleka kweemodyuli ekuququzeleleni uqhagamshelo olungenamthungo kunye nonxibelelwano luya kuqhubeka lukhula kuphela.
