IBand Stop Filter, (BSF) lolunye uhlobo lwesekethe ekhethiweyo esebenza ngokuthe ngqo ngendlela echaseneyo neBand Pass Filter esiyijongileyo ngaphambili. Isihluzo sokumisa ibhendi, ekwaziwa ngokuba sisihluzo sokulandula ibhendi, sidlula zonke iifrikhwensi ngaphandle kwezo zingaphakathi kwebhendi yokumisa echaziweyo ethotywe kakhulu.
Ukuba le bhendi yokumisa imxinwa kakhulu kwaye icuthelwe kakhulu ngaphezulu kwe-hertz embalwa, ke isihluzo sokumisa ibhendi siqhele ukubizwa ngokuba sisihluzo senotshi, njengoko impendulo yaso rhoqo ibonisa ukuba inotshi enzulu kunye nokukhetha okuphezulu (igophe elikwicala elisezantsi) kunebhendi ethe tyaba ebanzi.
Kwakhona, kanye njengesihluzo sokudlula ibhendi, i-band stop (i-band reject okanye i-notch) icebo lokucoca i-second-order (i-pole-pali) enee-frequencies ezimbini ezisikiweyo, ezibizwa ngokuba yi--3dB okanye i-half-power points ezivelisa i-band stop band bandwidth phakathi kwala manqaku mabini -3dB.
Emva koko umsebenzi we-band stop filter ugqithise kakhulu kuzo zonke ezo frikhwensi ukusuka ku-zero (DC) ukuya kuthi ga kwindawo yokuqala (esezantsi) yokunqunyulwa kwamaza ƒL, kwaye idlule zonke ezo frikhwensi ngaphezulu kwe-frequency yayo yesibini (phezulu) yokunqunyulwa ƒH, kodwa vala okanye ukhabe zonke ezo frikhwensi phakathi. Emva koko i-bandwidth yesihluzi, i-BW ichazwa njenge: (ƒH - ƒL).
Ke kwisihluzo sokumisa ibhendi ebanzi, izihluzi eyona bhendi yokumisa ilele phakathi kwamanqaku ayo asezantsi nangaphezulu -3dB njengoko ithoba, okanye yala nakuphi na ukuphindaphinda phakathi kwezi zihlandlo zimbini zisikiweyo. Ijiko lempendulo yefrikhwensi yesihluzo esifanelekileyo sokumisa ibhanti linikiwe.
Eyona nto ifanelekileyoband stop filterinokuba nokuthomalalisa okungapheliyo kwibhendi yayo yokumisa kunye no-zero attenuation kulo naliphi na ibhendi yokudlula. Utshintsho phakathi kweebhendi ezimbini zokupasa kunye nebhendi yokumisa iya kuba nkqo (udonga lwezitena). Kukho iindlela ezininzi esinokuyila ngayo "i-Band Stop Filter", kwaye zonke ziphumeza injongo enye.
Iiyunithi ziza kumgangatho kunye ne-SMA okanye i-N iziqhagamshelo zabasetyhini, okanye i-2.92mm, 2.40mm, kunye ne-1.85mm izihlanganisi zamacandelo aphezulu.
Singenza kwakhona iBand Stop Filterngokweemfuno zakho. Ungangenisa iphepha lokulungiselela ukubonelela ngeenkcukacha ozifunayo.
