Isihlungi se-RFTYT Lowhpass Esisetshenziselwa Ama-Transmitters, Receivers, ETC
Izihlungi ze-low-pass zisetshenziselwa ukudlulisa ngokusobala amasiginali wefrikhwensi ephezulu ngenkathi kuvimbela noma kuncishiswa izingxenye zemvamisa ngaphezu kwefrikhwensi ethile yokusika.
Isihlungi se-low-pass sinokungena okuphezulu ngaphansi kwe-cut-off frequency, okungukuthi, amasiginali adlula ngaphansi kwaleyo frikhwensi ngeke athinteke.Amasignali angaphezu kwe-cut-off frequency ancishiswa noma avinjwe isihlungi.

Ukucindezelwa kwe-RFTYT Highpass Filter Stopband
Izihlungi ze-High-pass zisetshenziselwa ukudlulisa amasignali efrikhwensi ephansi ngokusobala ngenkathi kuvimbela noma kuncishiswa izingxenye zemvamisa ngaphansi kwefrikhwensi ethile yokusika.
Isihlungi se-High-pass sine-cutoff frequency, eyaziwa nangokuthi i-cutoff threshold.Lokhu kubhekisela ebuningini lapho isihlungi siqala khona ukunciphisa isignali yefrikhwensi ephansi.Isibonelo, isihlungi se-high pass engu-10MHz sizovimba izingxenye zefrikhwensi ezingaphansi kuka-10MHz.

I-RFTYT Bandstop Filter Q Factor Frequency Range
Izihlungi ze-band-stop zinekhono lokuvimba noma ukunciphisa amasignali ebangeni elithile lefrikhwensi, kuyilapho amasiginali angaphandle kwalolo bubanzi ahlala ekhanyela.
Izihlungi ze-band-stop zinamafrikhwensi amabili anqamule, imvamisa yokusika ephansi kanye nefrikhwensi ephezulu yokusika, akha ibanga lefrikhwensi elibizwa ngokuthi “ibhendi yokungena”.Amasignali ebangeni le-passband ngeke athintwe yisihlungi.Izihlungi ze-band-stop zakha ububanzi befrikhwensi eyodwa noma ngaphezulu ebizwa ngokuthi “ama-stopbands” ngaphandle kwebanga le-passband.Isignali kububanzi be-stopband incishisiwe noma ivinjwe ngokuphelele isihlungi.
