Umuyoboro mwinshi wa bande ya filtri ni ibikoresho bya elegitoronike byashizweho kugirango yemere gusa urutonde rwihariye rwibimenyetso byihuta byanyura mugihe uhuza ibimenyetso kuri radiyo hanze yurwo rwego. Akayunguruzo gakoreshwa cyane muri sisitemu yitumanaho, ibikoresho byamajwi, nibindi bikoresho bya elegitoronike bisaba igisubizo nyacyo. Muri iyi nyandiko, tuzasesengura ibintu byingenzi biranga umurongo mwinshi wa bande ya filtri, harimo ibisubizo byabo, umurongo wa interineti, na Q-ibintu.
Igisubizo cya Frequency: Igisubizo cyinshuro yumurongo mwinshi wa bande ya filteri yerekana uburyo ihuza ibimenyetso kuri frequency hanze ya passband nuburyo byongerera ibimenyetso muri passband. Byashizweho neza-byihuta byihuta byanyuze muyunguruzi bizagira inzibacyuho ityaye hagati yumuhanda uhagarara, hamwe na ripple ntoya muri passband. Imiterere yumurongo wo gusubiza umurongo ugenwa nigishushanyo mbonera, kandi irashobora kurangwa numurongo wo hagati hamwe nubunini bwayo.
Umuyoboro mugari: Umuyoboro mugari wa bande ya bande ya pass ya filteri ni intera yumurongo wemerewe kunyura muyungurura hamwe na attenuation ntoya. Mubisanzwe byerekanwe nkitandukaniro riri hagati yumurongo wo hejuru nu munsi -3 dB, aribwo buryo bwo kuyungurura imbaraga zo kuyungurura kugabanukaho 50% ugereranije nimbaraga nini muri passband. Umuyoboro mugari wa bande yihuta ya bande ya filteri ni ikintu cyingenzi kigena guhitamo kwayo nuburyo ishobora kwanga ibimenyetso udashaka hanze ya passband.
Ikibazo-Ikibazo: Ikibazo-cyumuvuduko mwinshi wumurongo wa bande ya filteri ni igipimo cyo guhitamo kwayo cyangwa ubukana bwiyungurura inshuro. Byasobanuwe nkikigereranyo cya centre yinshuro yumurongo mugari. Ikirenga Q-ibintu bihuye nubunini bwagutse hamwe nigisubizo gikarishye, mugihe Q-yo hepfo ihuye numuyoboro mugari hamwe nigisubizo cya buhoro buhoro. Q-ibintu byumurongo mwinshi wa bande ya filteri ni ikintu cyingenzi kigena imikorere yacyo mukwanga ibimenyetso udashaka hanze ya passband.
Igihombo cyo Kwinjiza: Gutakaza igihombo cyumuvuduko mwinshi wa bande ya filteri ni umubare wibimenyetso byerekana igihe ibimenyetso byanyuze muyungurura. Ubusanzwe bigaragarira muri décibel kandi ni igipimo cyerekana uko akayunguruzo gahuza ibimenyetso muri passband. Byateguwe neza cyane ya bande ya bande ya filteri igomba kugira igihombo gito cyo kwinjiza muri passband kugirango wirinde gutesha agaciro ubwiza bwibimenyetso.
Guhuza Impedance: Guhuza Impedance ni ikintu cyingenzi kiranga umurongo mwinshi wa bande ya filtri, cyane cyane muri sisitemu yitumanaho. Iyinjiza nibisohoka impedance ya filteri igomba guhuzwa ninkomoko hamwe nuburemere bwimitwaro kugirango hagabanuke ibimenyetso byerekana no guhuza ibimenyetso. Ihuza neza cyane ya bande ya bande ya filteri izagira ibimenyetso bike byo gutakaza no kugoreka.
Mugusoza, umurongo mwinshi wa bande ya filtri nibintu byingenzi mubice bya elegitoronike bisaba igisubizo nyacyo. Ibyingenzi byabo byingenzi birimo inshuro zabo zisubiza, umurongo mugari, Q-ibintu, gutakaza kwinjiza, hamwe no guhuza impedance. Byashizweho neza cyane byumuvuduko mwinshi bande ya filteri igomba kugira igisubizo gikaze gisubiza, umurongo mugari, igihombo gito cyo kwinjiza, hamwe na impedance ihuye kugirango ikore neza.
