Isihluzi sokuPasa okuPhantsi
Izihluzi zokupasa okusezantsi zisetyenziselwa ukudlulisa ngokuphandle iisiginali eziphakamileyo ngelixa uvala okanye ucutha iinxalenye zamaza omoya ngaphezulu komjikelo othile wokusika.
Isihluzi esikwipasi elisezantsi sinokungena okuphezulu ngaphantsi kwe-frequency cut-off frequency, oko kukuthi, iisignali ezidlula ngaphantsi kweso sihlandlo aziyi kuchaphazeleka.Iimpawu ezingaphezulu kwe-cut-off frequency zithotywe okanye zivalwe sisihluzo.

I-RFTYT Highpass Filter Stopband Suppression
Izihluzi zokupasa okuphezulu zisetyenziselwa ukudlulisa iisiginali zefrikhwensi esezantsi ngokuphandle ngelixa zithintela okanye zithomalalisa amacandelo amaza ngaphantsi kwe-cutoff frequency ethile.
Isihluzi se-High-pass ine-cutoff frequency, ekwabizwa ngokuba yi-cutoff threshold.Oku kubhekiselele kuphindaphindo apho isihluzi siqala khona ukuthomalalisa umqondiso wefrikhwensi ephantsi.Umzekelo, i-10MHz yokucoca i-high-pass filter iya kuvala amacandelo angaphantsi kwe-10MHz.

I-RFTYT Bandstop Filter Q Factor Frequency Range
Izihluzi ze-band-stop ziyakwazi ukubhloka okanye zithobe imiqondiso kuluhlu oluthile lwamaza, ngelixa iisignali ezingaphandle kolo luhlu zihlala zingafihli.
Izihluzi ze-Band-stop zineefrikhwensi ezimbini zokuqhawula, i-low cutoff frequency kunye ne-high cutoff frequency, eyenza uluhlu lwamaza okubizwa ngokuba yi "passband".Iimpawu kuluhlu lokugqitha aziyi kuchaphazeleka kakhulu sisihluzo.Izihluzi ze-band-stop zenza uluhlu lwefrikhwensi enye okanye ngaphezulu ebizwa ngokuba "yi-stopbands" ngaphandle koluhlu lokugqitha.Umqondiso kuluhlu lwe-stopband luthotyiwe okanye luvalwe ngokupheleleyo sisihluzo.
