Marka loo eego sifooyinka isha faragelinta, kala duwanaanta soo noqnoqda, danab iyo impedance iyo xuduudaha kale iyo sifooyinka load ee shuruudaha, xulashada habboon ee filtarrada, guud ahaan tixgeli:
Mid ka mid ah, waxaa loo baahan yahay in filtarka faragelinta elektromagnetic buuxin karo sifooyinka attenuation iyo galinta shuruudaha lumin ee looga baahan yahay load gudahood band soo noqnoqda hawlgalka u dhiganta, iyo haddii qadar attenuation filter a buuxin karin shuruudaha, waxaa loo isticmaali karaa multistage, karaa hel attenuation ka sarreeya heerka hal mar, shaandhada kala duwan ee shaandhada, waxay heli kartaa sifooyin attenuation wanaagsan iyo luminta galinta bandband.
Marka labaad, si loo daboolo inta jeer ee hawlgalka wareegga culeyska iyo baahida loo qabo in la xakameeyo inta jeer ee shuruudaha, haddii inta jeer ee la xakameynayo iyo inta jeer ee calaamadaha waxtarka leh ay aad u dhow yihiin, waxaa lagama maarmaan ah in la yeesho sifooyinka soo noqnoqda ee aad u sarreeya shaandheynta, si loo daboolo xakamaynta shaandhada soo noqnoqda faragelinta, u oggolow oo keliya isticmaalka shuruudaha calaamadaha soo noqnoqda ee waxtarka leh.Seddexaad, inta jeer ee loo baahan yahay, xannibaadda shaandhada EMI filter RFI waa inay la mid tahay is-hortaagga isha faragelinta iyo culeyska culeyska ee ku xiran, iyo haddii culeysku yahay xannibaad sare, soo-saarka shaandhada korantadu waa inay ahaataa iska caabin hoose, iyo haddii Korontada ama is-hortaagga isha faragelinta ayaa ah hoos-u-dhac hooseeya, wax-soo-saarka filtarku waa inuu noqdaa iska caabin sare.
Haddii impedance awoodda ama impedance isha faragelinta aan la garanayn ama isbedel in kala duwan oo weyn, waa ay adag tahay in la helo sifooyinka shaandhaynta deggan, si ay u helaan filtarku leeyahay sifooyin shaandhayn wanaagsan xad deggan, waxay noqon kartaa in galitaanka filter iyo saarka, at isku mar ka dibna resistor go'an.
Afar, filtarku waa inuu lahaadaa iska caabin cadaadis gaar ah, marka loo eego tamarta iyo isha faragelinta ee korantada la qiimeeyay si loo doorto shaandhada korantada, si ay u leedahay koronto ku filan oo ku filan, si loo hubiyo in dhammaan xaaladaha shaqada ee la filayo ay noqon karaan hawlgal lagu kalsoonaan karo. , waxay u adkeysan kartaa saameynta gelinta cadaadis sare oo degdeg ah.Shan, shaandhada korantadu waxay u oggolaanaysaa gudbinta inay la jaanqaado heerka hadda la qiimeeyay ee si joogto ah ugu socda wareegga.
Hadda sare ee go'an waxay kordhin doontaa mugga iyo miisaanka shaandhada EMI, iyo hadda go'an ee hooseeya wuxuu yareynayaa kalsoonida shaandhada EMI.Lix, shaandhada korantadu waa inay lahaataa xoog farsamo oo ku filan, qaab dhismeedka fudud, miisaanka fudud, cabbirka yar, fududahay in la rakibo, ammaan ah oo la isku halleyn karo.
