Ukukhangela kwirediyo

Kukhangelo lukanomathotholo, iiamplifiers zisetyenziswa ngokubanzi ukukhulisa umqondiso kunye nolawulo lokuzuza.Ngokukodwa, ii-amplifiers zisetyenziselwa ukunyusa umqondiso ofunyenwe kwisixhobo sokufumana i-decoding efanelekileyo kunye nokucubungula.Kwangaxeshanye, kwiinkqubo zokukhangela kwirediyo, ii-amplifiers zingasetyenziselwa ukulawula ukuhanjiswa komqondiso phakathi kwezixhobo ukuthintela imiqondiso ekubeni yomelele kakhulu okanye ibe buthathaka kakhulu, ukuze inkqubo isebenze ngokuzinzileyo nangokufanelekileyo.Ngokufanayo, kwizixhobo zenqwelomoya, ii-amplifiers zinokusetyenziswa ukulawula imiqondiso yeeparamitha ezinjengobude kunye nesantya ukuze abaqhubi bakwazi ukuyilawula ngokuchanekileyo inqwelo-moya.Ngamafutshane, ii-amplifiers zisetyenziswa kakhulu kukhangelo lukanomathotholo kwaye zinokusetyenziswa naphi na apho kufuneka uphuculo lwesignali okanye ugqithiso lwesignali yolawulo.
