IyoSefa yeBhendi, (BSF) imhando yedunhu rinosarudza mafrequency rinoshanda nenzira yakasiyana chaizvo neBand Pass Filter yatakambotarisa. Bhandi rinomisa maband, rinozivikanwawo sebhendi rinoramba maband, rinopfuura mafrequency ese kunze kweaya ari mukati mebhendi rinomisa rakatarwa iro rakadzikira zvakanyanya.
Kana bhendi iri restop rakamanikana uye rakadzikira zvakanyanya pamusoro pemahertz mashoma, saka firita restop reband rinowanzonzi firita renotch, sezvo mhinduro yaro yefrequency inoratidza iyo ye deep notch ine selectivity yakakwira (steep-side curve) pane bhendi rakafara rakatsetseka.
Uyewo, kungofanana nefirita yekufambisa band, firita yeband stop (band reject kana notch) ifirita yepiri (two-pole) ine ma frequency maviri akachekwa, anozivikanwa se -3dB kana kuti half-power points achigadzira bandwidth yeband stop yakafara pakati peaya ma -3dB points maviri.
Zvadaro basa rebhendi rekumisa firita nderekuti ripfuure mafrequencies ese kubva pazero (DC) kusvika padanho rayo rekutanga (repasi) rekucheka frequency ƒL, uye ripfuure mafrequencies ese ari pamusoro pefrequency yechipiri (yepamusoro) yekucheka ƒH, asi rivhare kana kuramba mafrequencies ese ari pakati. Zvadaro bandwidth yemafirita, BW inotsanangurwa se: (ƒH – ƒL).
Saka kana iri firita rebhandi rakafara, firita rebhandi chairo remafirita riri pakati pemapoinzi ayo epasi neepamusoro e -3dB parinodzikira, kana kuramba chero frequency pakati pemafrequencies maviri aya akachekwa. Saka curve yemhinduro yefrequencies yebhendi rakakwana inopihwa.
Zvakanakisabhendi yekumisa firitayaizova nekudzikira kusingaperi mubhendi rayo rekumira uye kudzikira kwezero mubhendi repasi. Kuchinjana pakati pemabhendi maviri ekumira nebhendi rekumira kwaizova kwakamira (madziro ezvidhinha). Pane nzira dzakawanda dzatingagadzira "Band Stop Filter", uye dzese dzinoita chinangwa chimwe chete.
