(1) isihluzo sokupasa esisezantsi
Ukusuka kwi-0 ukuya kwi-F2, iimpawu ze-amplitude-frequency zithe tyaba, ezinokuthi zenze ukuba iinqununu ze-frequency ezingaphantsi kwe-F2 zidlule phantse zingagxilwanga, ngelixa ezo ziphakamileyo kune-F2 ziyancipha kakhulu.
(2) isihluzo esiphakamileyo
Ngokuchaseneyo nokucoca okuphantsi, iimpawu zayo ze-amplitude-frequency zisicaba ukusuka kwi-F1 ukuya kwi-infinity.Ivumela amacandelo e-frequency yesiginali engentla kwe-F1 ukuba idlule iphantse ingabinamdla, ngelixa ezo zingaphantsi kwe-F1 ziya kuthotywa kakhulu.
(3) isihluzo sokupasa band
I-passband yayo iphakathi kwe-F1 kunye ne-F2.Ivumela amacandelo e-frequency yesiginali ephezulu kune-F1 kwaye isezantsi kune-F2 ukuba idlule ngokungakhathalelwanga, ngelixa amanye amacandelo encitshisiwe.
(4) isihluzo sokumisa ibhanti
Ngokuchaseneyo nokucoca i-bandpass, i-stop band iphakathi kwe-frequencies F1 kunye ne-F2.Ithomalalisa amacandelo e-frequency yesiginali ephezulu kune-F1 kwaye isezantsi kune-F2, kwaye amanye amacandelo e-frequency adlula phantse angajongwanga.
I-electromagnetic interference (EMI) isihluzi samandla sisixhobo esingenakwenziwa esenziwe nge-inductance kunye ne-capacitance.Isebenza ngokwenyani njengezihluzo ezimbini zokupasa okusezantsi, enye ithoba isiphazamiso sendlela eqhelekileyo kwaye enye ithomalalisa uphazamiso lwendlela eyahlukileyo.Ithomalalisa amandla e-rf kwibhendi yokumisa (idla ngokuba mkhulu kune-10KHz) kwaye ivumela amaza ombane ukuba adlule ngokuncitshiswa okuncinci okanye akukho.Izihluzi zamandla e-EMI lukhetho lokuqala kwiinjineli zoyilo lwe-elektroniki ukulawula ukwenziwa kunye ne-radiated EMI.
(A) Ngokusebenzisa iimpawu ze-capacitor edlula i-frequency ephezulu kunye ne-low frequency isolation, i-high frequency interference current yocingo oluphilayo kunye nocingo olungathathi hlangothi lungeniswa kwi-wire yomhlaba (indlela eqhelekileyo), okanye i-high frequency interference current yocingo oluphilayo luyaziswa. kwintambo engathathi hlangothi (indlela eyahlukileyo);
(B) Ukubonakalisa ukuphazamiseka kwe-high-frequency interference ngoku umva kumthombo wokuphazamiseka ngokusebenzisa iimpawu ze-impedance ze-coil inductor;
Ukunciphisa ukuxhathisa komhlaba, isihluzi kufuneka sifakwe kumphezulu wesinyithi oqhubayo okanye siqhagamshelwe kwindawo yomhlaba ekufutshane ngendawo yomhlaba ephothiweyo ukunqanda uthintelo olukhulu lokumisa olubangelwa ziingcingo ezicekethekileyo zokumisa.
Izalathisi ezininzi kufuneka ziqwalaselwe xa ukhetha isihluzo somgca wamandla.Eyokuqala ilinganiswe nge-voltage / yangoku, ilandelwa yilahleko yokufaka, ukuvuza kwangoku (isihluzo samandla e-dc asiqwalaseli ubungakanani bokuvuza kwangoku), ubungakanani besakhiwo, kwaye ekugqibeleni luvavanyo lombane.Ekubeni ingaphakathi lesihluzi lihlala liyimbiza, iimpawu zokusingqongileyo aziyongxaki enkulu.Nangona kunjalo, iimpawu zeqondo lokushisa lezinto zokubumba kunye ne-capacitor yokucoca zinempembelelo ethile kwiimpawu zokusingqongileyo zokucoca umbane.
Umthamo wesihluzi ugqitywe ikakhulu yi-inductance kwisekethe yokucoca.Ubuninzi bomthamo wekhoyili ye-inductance, ubukhulu bomthamo wesihluzi.
