Intangiriro ku bipimo by'imikorere ya firiti - Igice cya 2

Kubera ko ibyuma biyungurura, kimwe n'ibindi bicuruzwa byakozwe n'abantu, bidashobora gukorwa kugira ngo bihuze neza n'ibikubiye mu gitabo cy'amabwiriza, hari agaciro kemewe gakwiye kugaragazwa. Ku mashini ziyungurura za narrowband, ibipimo by'ingenzi bigomba gutangwaho ubushobozi bwo kwihanganira ni: uburebure bw'umurambararo, uburebure bw'umurambararo, na bandwidth, kuko hafi ya zose uko uburebure bw'umurambararo buba buri hejuru niko biba byiza, kandi akenshi birahagije kugaragaza aho ntarengwa. Ku bushobozi bwo kwihanganira uburebure bw'umurambararo hari ibintu bibiri by'ingenzi. Icya mbere ni uburinganire bw'uburebure bw'umurambararo hejuru y'ubuso bwa filter. Hazabaho itandukaniro rimwe na rimwe, nubwo ari rito cyane, muri filime, ariko hagomba gutangwa umupaka. Icya kabiri, ikosa mu gupima uburebure bw'umurambararo ku gice cyose cya filter. Iyi mfashanyigisho akenshi iba nziza, ku buryo filter ishobora guhora ihengamye kugira ngo ihuze n'uburebure bw'umurambararo bukwiye. Ku bushobozi bw'umurambararo runaka, ingano y'ubuhengamire bwemerewe mu ikoreshwa iryo ari ryo ryose izagenwa ku rugero runini n'umurambararo w'uburyo bwo kureba, kuko uko inguni yo kuhengamira yiyongera, urwego rwuzuye rw'inguni icyuma gishobora kwemera rugabanuka.

Umurambararo w'umuyoboro wa filter nawo ugomba kugaragazwa no guhabwa uburenganzira, ariko kubera ingorane zo kugenzura umurambararo neza cyane, ubusanzwe ntibishoboka kugabanya umurambararo w'umuyoboro cyane, kandi uburenganzira bugomba kuba bunini bushoboka, muri rusange butari munsi y'inshuro 0.2 z'agaciro kagenwe, keretse iyo hari ibisabwa byihariye kuri wo.
Indi ngingo y'ingenzi mu gipimo cy'imikorere y'urumuri ni uguhagarika mu gace gahagarika, gashobora gusobanurwa mu buryo butandukanye, haba nk'impuzandengo y'ihererekanya ry'urumuri ku rugero rwose, cyangwa nk'ihererekanya ry'urumuri ku rugero rwose ku bunini bw'urumuri, byombi bishobora gutanga umupaka wo hejuru. Iya mbere ikunze gukoreshwa iyo isoko ry'ihungabana ari spectrum ihoraho, iya kabiri ikajya ku isoko y'umurongo, muri icyo gihe ubunini bw'urumuri bukoreshwa, niba buzwi, bugomba kugaragazwa.
Ubundi buryo butandukanye bwo kugaragaza imikorere ya filter ni ugushushanya ibahasha ntarengwa n’iyoroheje y’ihindagurika ry’uburyo bwo kohereza hakoreshejwe uburebure bw’umurambararo. Imikorere ya filter ntigomba kuba hanze y’agace gatwikiriwe n’ibahasha; ni ngombwa ko inguni yo kwakira filter nayo igomba kugaragazwa. Ubu bwoko bwa metric burumvikana kurusha ubwa mbere bwavuzwe haruguru, icyakora, ikosa rimwe muri ubu buryo ni uko uburyo busobanura buri sano mu buryo bwuzuye, bishobora kuba bigoye cyane iyo gukoresha agaciro mpuzandengo bishobora kuba bikwiye. Byongeye kandi, ntibishoboka gushushanya ikizamini cyo kumenya niba filter yujuje ubu bwoko bwa metric burundu, kandi uburebure bw’umurambararo bw’igikoresho cyo gupima bugira ingaruka. Kubwibyo, niba filter zigomba gusobanurwa muri ubu buryo, ni byiza ko hashyirwamo inyandiko ivuga ko imikorere ya filter ivugwa kuri buri uburebure bw’umurambararo ari impuzandengo y’imikorere mu bihe bimwe na bimwe. Muri rusange, ibisobanuro by’ibipimo by’imikorere ya optique byakozwe nta mpamvu nyinshi zikenewe. Mu ikoreshwa rimwe gusa, ibi bintu bizagaragaza urwego rutandukanye rw'ingenzi, kandi buri rubanza rugomba gusuzumwa cyane mu rwego rw'intego zarwo. Biragaragara ko muri uru rwego ari ngombwa ko akazi k'umushushanyi wa sisitemu gahuzwa cyane n'ak'umushushanyi wa filter.
