Intshayelelo kwisihluzi sokwala ibhendi

I-Cheng du leader microwave Tech., (leader-mw) I-Band Reject Filter (ekwaziwa ngokuba yi-bandstop filter okanye i-BSF), icandelo elikhethekileyo elidlala indima ebalulekileyo ekulawuleni iinxalenye ze-frequency zesignali. Ngokungafaniyo ne-band-pass filter eqhelekileyo, evumela uninzi lweenxalenye ze-frequency ukuba zidlule ngelixa zinciphisa uluhlu oluthile, i-band reject filter isebenza ngendlela eyahlukileyo. Ivumela uninzi lweenxalenye ze-frequency ukuba zidlule, kodwa inciphisa uluhlu oluthile lweenxalenye ze-frequency ukuya kumanqanaba aphantsi kakhulu.

Olu phawu lukhethekileyo lwenza isihluzo sethu se-band reject silungele usetyenziso apho uluhlu oluthile lwe-frequency kufuneka lususwe okanye luncitshiswe kakhulu. Nokuba ufuna ukususa ukuphazamiseka okungafunekiyo okanye ukucoca amaza athile engxolo, isihluzo sethu se-band reject senzelwe ukubonelela ngokusebenza okugqwesileyo kunye nokuchaneka.

Isihluzi se-band reject luhlobo olukhethekileyo lwesihluzi se-band-stop, kunye ne-stopband scope yaso encinci kakhulu. Oku kuqinisekisa ukuba uluhlu lwefrikhwensi ekujoliswe kuyo kuphela oluncitshiswa ngokufanelekileyo, nto leyo eshiya yonke isignali ingasebenzi. Eli nqanaba lokuchaneka libaluleke kakhulu kumashishini amaninzi, kuquka unxibelelwano, ukucubungula isandi, kunye nezixhobo ze-elektroniki.
