IIsihluzi sokuMisa iBhendi, (BSF) lolunye uhlobo lwesekethe ekhetha amaza ombane esebenza ngendlela eyahlukileyo kwiBand Pass Filter ebesiyijongile ngaphambili. I-band stop filter, eyaziwa ngokuba yi-band reject filter, idlula zonke ii-frequencies ngaphandle kwezo zikwi-stop band ethile ezinciphile kakhulu.
Ukuba le stop band incinci kakhulu kwaye inciphile kakhulu kwi-hertz ezimbalwa, ngoko ke i-band stop filter idla ngokubizwa ngokuba yi-notch filter, njengoko impendulo yayo ye-frequency ibonisa i-deep notch enokukhetha okuphezulu (i-steep-side curve) endaweni ye-flatted wider band.
Kwakhona, njengesihluzi sebhendi esidlulayo, isihluzi sebhendi yokumisa (ibhendi yokugatya okanye i-notch) sisihluzi sesibini (seepali ezimbini) esineefrikhwensi ezimbini ezinqumliweyo, ezaziwa ngokuba zii--3dB okanye ii-half-power points ezivelisa i-wide stop band bandwidth phakathi kwezi points zimbini ze--3dB.
Emva koko umsebenzi wesihluzi sebhendi yokumisa kukudlula kakhulu zonke ezo frequencies ukusuka ku-zero (DC) ukuya kwi-clock-off frequency point yayo yokuqala (esezantsi) ƒL, kwaye idlule zonke ezo frequencies ngaphezulu kwe-clock-off frequency yayo yesibini (ephezulu) ƒH, kodwa ivale okanye ilahle zonke ezo frequencies eziphakathi. Emva koko i-bandwidth yezihluzi, i-BW ichazwa ngolu hlobo: (ƒH – ƒL).
Ngoko ke kwisihluzi sokumisa ibhendi ebanzi, ibhendi yokumisa yokwenyani yezihluzi iphakathi kwamanqaku ayo asezantsi naphezulu e-3dB njengoko incipha, okanye ilandula naluphi na uphindaphindo phakathi kwezi frequencies zimbini zokusika. Ke ngoko kunikwe i-curve yempendulo yophindaphindo yesihluzi sokumisa ibhendi esifanelekileyo.
Eyona nto ifanelekileyoisihluzi sokumisa ibhendiibiya kuba nokuncitshiswa okungapheliyo kwibhendi yayo yokumisa kunye nokuncitshiswa okungekhoyo kuyo nayiphi na ibhendi yokumisa. Utshintsho phakathi kwamaqela amabini okupasa kunye nebhendi yokumisa luya kuba ngokuthe nkqo (udonga lwezitena). Kukho iindlela ezahlukeneyo esinokuyila ngazo "iBand Stop Filter", kwaye zonke zifezekisa injongo enye.
Iiyunithi ziza nezihlanganisi ze-SMA okanye ze-N ezisemgangathweni, okanye izihlanganisi ze-2.92mm, 2.40mm, kunye ne-1.85mm zezixhobo ezisebenzisa i-frequency ephezulu.
Singakwazi nokwenza ngokwezifisoIsihluzi sokuMisa iBhendingokweemfuno zakho. Ungangena kwiphepha lokwenza ngokwezifiso ukuze unikezele ngeenkcukacha ozifunayo.
