Tikatumiza chizindikiro, kaya ndi chizindikiro cha kuwala kapena chizindikiro cha magetsi kapena chizindikiro chopanda zingwe, ngati chikuperekedwa mwachindunji, chizindikirocho chimatha kusokoneza phokoso, ndipo n'zovuta kupeza chidziwitso choyenera pamapeto olandira. Pofuna kupititsa patsogolo mphamvu yotsutsa-kusokoneza dongosolo, zikhoza kuzindikirika mwa kusintha chizindikiro. Kusinthasintha kungathenso kuwongolera kuchuluka kwa kagwiritsidwe ntchito ka tchanelo, motero kusinthasintha kumakhudza kwambiri magwiridwe antchito komanso kudalirika kwa njira yolumikizirana.
Kusinthasintha kwa Angle komwe kufotokozedwa pansipa ndi kwa ma analogi.
Sinusoidal chonyamulira ali magawo atatu: matalikidwe, pafupipafupi ndi gawo. Tikhoza kutsegula zambiri za chizindikiro modulated osati mu matalikidwe kusintha chonyamulira, komanso pafupipafupi kapena gawo kusintha chonyamulira. Panthawi yosinthira, ngati ma frequency a chonyamulira akusintha ndi chizindikiro chosinthidwa, amatchedwa frequency modulation kapena frequency modulation (FM); Ngati gawo la chonyamulira likusintha ndi siginecha yosinthidwa, imatchedwa gawo modulation kapena phase modulation (PM). Mu njira ziwirizi zosinthira, matalikidwe a chonyamulira amakhalabe nthawi zonse, pamene kusintha kwafupipafupi ndi gawo kumawonetseredwa monga kusintha kwa nthawi yomweyo ya chonyamuliracho, kotero kuti kusinthasintha kwafupipafupi ndi kusinthasintha kwa gawo kumatchulidwa pamodzi monga kusinthasintha kwa Angle.
Kusiyanitsa pakati pa Angle modulation ndi matalikidwe a matalikidwe ndikuti mawonekedwe a sipekitiramu osinthika sakhalanso kusuntha kwa mzere wa sipekitiramu yoyambira yosinthika, koma kusinthika kosagwirizana kwa sipekitiramu, komwe kudzatulutsa zigawo zatsopano zamtundu wosiyana ndi kusintha kwa sipekitiramu. amatchedwanso kusinthasintha kosagwirizana.
Onse a FM ndi PM amagwiritsidwa ntchito kwambiri pamakina olankhulirana. Ma FM amagwiritsidwa ntchito kwambiri pakuwulutsa nyimbo zodalirika kwambiri, kutumiza ma siginecha aku TV, kuyankhulana kwa satellite ndi mafoni am'manja. Kuphatikiza pa kugwiritsidwa ntchito mwachindunji pakufalitsa, PM imagwiritsidwanso ntchito ngati njira yosinthira mwachindunji ma siginecha a FM. Pali mgwirizano wapakati pakati pa kusinthasintha kwafupipafupi ndi kusintha kwa gawo.
Poyerekeza ndi kusinthasintha kwa matalikidwe, mwayi wodziwika kwambiri wa kusinthasintha kwa Angle ndikuchita kwake kwakukulu kotsutsa phokoso. Komabe, pali kusinthanitsa pakati pa zopindula ndi zotayika, ndipo mtengo wa mwayiwu ndikuti kusinthasintha kwa Angle kumakhala ndi bandwidth yotakata kuposa ma siginecha osinthika.
Zomwe zili pamwambapa ndi Shenzhen HDV Phoelectron Technology Co., Ltd. kuti mubweretse chidziwitso cha "nonlinear modulation (Angle modulation)". Shenzhen HDV Phoelectron Technology Co., Ltd. imadalira kwambiri zinthu zoyankhulirana zomwe zimapangidwira opanga, kupanga zida zamakono zimakwirira:ONUmndandanda, optical module series,OLTseries, transceiver series. Itha kupereka ntchito zosinthidwa pazosintha zosiyanasiyana za zosowa za netiweki, kulandiridwa kuti mudzakambirane.
