    Guhindura umurongo (Guhindura inguni)

    Igihe cyo kohereza: Nzeri-12-2024

    Iyo twohereje ikimenyetso, cyaba ari ikimenyetso cya optique cyangwa ikimenyetso cyamashanyarazi cyangwa ikimenyetso kitagira umugozi, niba cyatanzwe muburyo butaziguye, ikimenyetso gishobora kwangiriza urusaku, kandi biragoye kubona amakuru yukuri kurangiza. Kugirango tunoze ubushobozi bwo kurwanya-kwivanga kwa sisitemu, birashobora kugerwaho muguhindura ibimenyetso. Guhindura birashobora kandi kunoza igipimo cyo gukoresha umuyoboro, modulation rero igira ingaruka zikomeye kumikorere no kwizerwa bya sisitemu yitumanaho.
    Guhindura inguni byasobanuwe hepfo ni kubimenyetso bisa.

    Umwikorezi wa Sinusoidal afite ibipimo bitatu: amplitude, frequency and phase. Turashobora kwipakurura amakuru yikimenyetso cyahinduwe ntabwo ari impinduka ya amplitude gusa yuwitwaye, ahubwo no mubihe byinshi cyangwa impinduka zicyiciro cyabatwara. Mugihe cyo guhindura, niba inshuro yabatwara ihinduka hamwe nibimenyetso byahinduwe, byitwa modulation modulation cyangwa modulation modulation (FM); Niba icyiciro cyabatwara gihindutse hamwe nikimenyetso cyahinduwe, byitwa icyiciro cyo guhindura cyangwa icyiciro (PM). Muri ubu buryo bubiri bwo guhindura ibintu, amplitude yuwitwaye ikomeza guhoraho, mugihe ihinduka ryinshuro nicyiciro bigaragazwa nkimpinduka mugice cyihuse cyikinyabiziga, bityo modulisiyo yumurongo hamwe na modulasiyo hamwe hamwe byitwa Angle modulation.

    Itandukaniro riri hagati ya Angle modulation na amplitude modulasiyo ni uko ibimenyetso byahinduwe byerekana ibimenyetso bitakiri umurongo uhinduranya wumwimerere wahinduwe ibimenyetso byerekana ibimenyetso, ahubwo ni umurongo utari umurongo uhinduranya ibintu, bizabyara ibice bishya byinshyi bitandukanye no guhinduranya ibintu, bityo rero nanone bita modulaire modulation.

    Byombi FM na PM bikoreshwa cyane muri sisitemu yitumanaho. FM ikoreshwa cyane mugutangaza umuziki wizerwa cyane, gutangaza amajwi ya TV, itumanaho rya satelite na sisitemu ya terefone ngendanwa. Usibye gukoreshwa mu buryo butaziguye, PM ikoreshwa kandi nk'inzibacyuho mu buryo butaziguye ibimenyetso bya FM. Hariho isano ya hafi hagati yo guhinduranya inshuro no guhinduranya icyiciro.

    Ugereranije na amplitude modulation, inyungu igaragara ya Angle modulation ni imikorere yayo yo kurwanya urusaku. Nyamara, hariho ubucuruzi hagati yinyungu nigihombo, kandi ikiguzi cyiyi nyungu nuko impinduka ya Angle ifata umurongo mugari kuruta ibimenyetso byahinduwe na amplitude.

    Ibyavuzwe haruguru ni Shenzhen HDV Phoelectron Technology Co., Ltd. kugirango uzane ubumenyi bwa "nonlinear modulation (Angle modulation)". Shenzhen HDV Phoelectron Technology Co., Ltd ishingiye cyane cyane kubicuruzwa byitumanaho kugirango bikorwe nababikora, umusaruro wibikoresho bikubiyemo:ONUurukurikirane, optique module ikurikirana,OLTurukurikirane, urukurikirane. Irashobora gutanga serivisi yihariye kubintu bitandukanye bikenerwa nurusobe, ikaze kuza kugisha inama.
