ItsindaAkayunguruzo ko guhagarika umugozi, (BSF) ni ubundi bwoko bwa frequencie selective circuit ikora mu buryo bunyuranye neza na Band Pass Filter twarebye mbere. Band stop filter, izwi kandi nka band reject filter, inyura kuri frequencies zose usibye izo muri stop band runaka zagabanutse cyane.
Niba iyi stop band ari nto cyane kandi ikaba yagabanutse cyane kuri hezite nke, icyo gihe stop filter ikunze kwitwa filter y'ibanga, kuko frequency response yayo igaragaza ubwinshi bw'ibanga rifite umwihariko wo guhitamo (ibanga rirambuye) aho kuba stop band nini.
Nanone, kimwe n'akayunguruzo k'ingufu, akayunguruzo k'ingufu (band reject cyangwa notch) ni akayunguruzo k'uburyo bwa kabiri (two-pole) gafite imirongo ibiri yo gukata, izwi cyane nka -3dB cyangwa igice cy'ingufu zitanga umurongo munini w'ingufu zo guhagarara hagati y'izi ngingo ebyiri -3dB.
Hanyuma imikorere ya filter yo guhagarika umurongo ni ugucisha iyo miyoboro yose kuva kuri zeru (DC) kugeza ku gice cyayo cya mbere (cyo hasi) cy'umuvuduko w'ingufu ƒL, no gusubika iyo miyoboro yose iri hejuru ya frequence yayo ya kabiri (yo hejuru) y'umuvuduko w'ingufu ƒH, ariko igahagarika cyangwa ikanze iyo miyoboro yose iri hagati. Hanyuma bandwidth ya filters, BW isobanurwa nka: (ƒH – ƒL).
Rero kuri filter ya "wide-band band stop", filters nyayo stop band iri hagati y'ingingo zayo zo hasi n'izo hejuru za -3dB uko igabanuka, cyangwa ikanze frequency iyo ari yo yose iri hagati y'izi frequencies ebyiri zo guhagarika. Bityo rero, frequencies ya filter ya "band stop" iratangwa.
Igitekerezo cyizaakayunguruzo ko guhagarika umugoziByaba bifite uburinzi butagira iherezo mu gice cyabyo cyo guhagarara kandi nta burinzi muri buri gice cyo guhagarara. Impinduka hagati y’imirongo ibiri yo guhagarara n’igice cyo guhagarara byaba bihagaze (urukuta rw’amatafari). Hari uburyo bwinshi dushobora gushushanya "Akayunguruzo ko Guhagarara k’Umutwe", kandi byose bisohoza intego imwe.
Ibikoresho biza bifite ibihuza bya SMA cyangwa N by’abagore, cyangwa ibihuza bya 2.92mm, 2.40mm, na 1.85mm ku bikoresho bifite umurongo munini w’itumanaho.
