Mwisi yisi yihuta yubuhanga bugezweho, igitekerezo cya modulator gifite uruhare runini kandi rwibanze mumikorere yibikoresho na sisitemu zitandukanye.Abayoborani ibice byingenzi bikoreshwa muguhindura no gukoresha ibimenyetso muburyo butandukanye bwa porogaramu zirimo itumanaho, gutangaza no kohereza amakuru.Mugihe ikoranabuhanga rikomeje gutera imbere no gutera imbere, akamaro ka modulator mu koroshya itumanaho ryiza kandi ryiza ntirishobora kuvugwa.
Muri elegitoroniki n'itumanaho, modulator ni igikoresho cyangwa umuzunguruko ushinzwe gushakisha amakuru ku kimenyetso cyitwara kugirango cyohereze.Ihindura cyane amakuru kuva muburyo bwumwimerere muburyo bukwiranye no kohereza muburyo bwihariye.Iyi nzira ningirakamaro kugirango amakuru atangwe kandi yakirwe neza aho agenewe.
Imwe mumikorere yingenzi ya modulator ni mubitumanaho, aho bikoreshwa mugukwirakwiza amajwi, amakuru nibimenyetso bya videwo kumurongo utumanaho.Muri sisitemu yitumanaho rya digitale, modulator ikoreshwa muguhindura amakuru ya digitale mubimenyetso bisa bishobora noneho koherezwa kumuyoboro w'itumanaho.Ubu buryo butuma ihererekanyabubasha ryamakuru yamakuru yibikorwa remezo bihari, bigafasha kwihuta kwamakuru no gutumanaho kwizewe.
Byongeye kandi,abayobora bigira uruhare runini mugutangaza no kwidagadura, bikoreshwa mugukwirakwiza televiziyo na radio.Ibiganiro kuri tereviziyo, kurugero, byishingikiriza kubayobora kugirango bahindure ibimenyetso byamajwi na videwo muburyo bushobora kwerekanwa kuri radiyo cyangwa binyuze mumiyoboro ya kabili na satelite.Mu buryo nk'ubwo, amaradiyo akoresha abayobora kugirango bashireho amajwi amajwi kumurongo wabatwara kugirango wohereze kubakira.
Usibye itumanaho no gutangaza amakuru, modulator nayo ni ngombwa mubijyanye no kohereza amakuru no guhuza imiyoboro.Mumurongo wa mudasobwa, modulator ikoreshwa muguhindura imibare ya digitale mubimenyetso byamashanyarazi cyangwa optique yo kohereza mumiyoboro y'itumanaho cyangwa insinga.Ibi bifasha guhanahana amakuru hagati yibikoresho na sisitemu bihujwe, byorohereza imikorere yimikorere yamakuru agezweho.
Iterambere mu buhanga bwa modulator ryanatumye habaho iterambere ryimikorere igoye ishobora guhindura neza uburyo bwo kohereza no kwakira.Ikoranabuhanga nka amplitude modulation (AM), modulation modulation (FM), hamwe na modulasiyo (PM) ikoreshwa muburyo bwo gutumanaho neza kandi byizewe.Izi gahunda zo guhindura zirashobora gushira amakuru kumatwara yikimenyetso cyukuri kandi ikemerera ibimenyetso koherezwa mumwanya muremure nta gihombo cyangwa gutesha agaciro.
Mugihe icyifuzo cyitumanaho ryihuse no kohereza amakuru bikomeje kwiyongera, uruhare rwabayobora mubuhanga bugezweho rukomeje kuba ingenzi.Iterambere ryikoranabuhanga rigezweho rya modulator ryatanze inzira yubushobozi bwitumanaho ryogukwirakwiza amajwi, amakuru nibimenyetso bya videwo muburyo butandukanye bwitumanaho.
Muri make,abayoboranibice byingenzi byikoranabuhanga rigezweho kandi bigira uruhare runini mugutanga amakuru neza mumiyoboro itandukanye.Kuva mu itumanaho no gutangaza amakuru kugeza no guhererekanya amakuru no guhuza imiyoboro, abayobora bari ku isonga mu gushoboza itumanaho ryizewe kandi neza.Mugihe ikoranabuhanga rikomeje gutera imbere, akamaro ka modulator mu korohereza imiyoboro itumanaho kandi itumanaho bizakomeza kwiyongera.
