Horumarinta tignoolajiyada shaandhaynta isku xirka korantada, tignoolajiyada shaandhaynta ayaa aad waxtar ugu leh xakamaynta faragelinta korantada, gaar ahaan calaamadda EMI ee wareejinta sahayda korontada, taas oo door wanaagsan ka ciyaari karta faragelinta faragelinta iyo shucaaca faragelinta.Calaamadaha faragelinta qaabka kala duwan iyo calaamadaha faragelinta habka caadiga ah waxay matali karaan dhammaan calaamadaha faragelinta korantada.
Midka hore wuxuu inta badan tilmaamayaa calaamada faragelinta ee ay isku gudbiyaan labada fiilo, kaas oo iska leh faragelinta summadaha waxaana lagu gartaa soo noqnoqoshada hooseeya, baaxadda faragelinta yar iyo faragelinta korantada ee yar ee abuurta.Midda dambe waxay inta badan ka hadlaysaa gudbinta calaamadaha faragelinta ee u dhexeeya fiilada iyo xayndaabka (dhulka), taas oo ka tirsan faragelinta asymmetric, waxaana lagu gartaa soo noqnoqoshada sare, baaxadda faragelinta ballaaran iyo faragelinta koronto-magneeteedka weyn.
Iyada oo ku saleysan falanqaynta sare, calaamadda EMI waxaa lagu xakameyn karaa ka hooseysa heerka xaddidan ee lagu qeexay halbeegyada EMI si loo gaaro ujeedada dhimista faragelinta.Marka lagu daro xakamaynta wax ku oolka ah ee ilaha faragelinta, filtarrada EMI ee lagu rakibay wareegyada soo-gelinta iyo soo-saarka ee sahayda beddelka ayaa sidoo kale ah hab muhiim ah oo lagu xakameynayo faragelinta korantada.Inta jeer ee caadiga ah ee ay ku shaqeeyaan aaladaha elektiroonigga ah waxay u dhexeeyaan 10MHz iyo 50MHz.Qaar badan oo ka mid ah halbeegga EMC ee heerka ugu hooseeya ee faragelinta korantada ee xadka 10 MHZ, ee loogu talagalay soo noqnoqda sare ee korontada EMI signal, ilaa iyo inta doorashada qaab dhismeedka shabakadu uu yahay mid fudud shaandhada EMI ama kala-goynta wareegga filter-ka EMI waa mid fudud, ma aha oo kaliya ayaa la gaari karaa Ujeedada lagu dhimayo xoojinta soo noqnoqoshada sare ee qaabka caadiga ah ee hadda jira, sidoo kale waxay qancin kartaa saameynta shaandhaynta ee xeerarka EMC.
Mabda'a naqshadeynta ee isku xirka korantada filter wuxuu ku salaysan yahay mabda'a sare.Waxaa jira dhibaatada faragelinta wadajirka ah ee u dhexeysa qalabka korontada iyo korontada iyo inta u dhexeysa qalabka korantada ee kala duwan, iyo xiriyaha korantada shaandhada ayaa ah doorasho ku habboon si loo yareeyo faragelinta.Maadaama pin kasta oo ka mid ah isku xirka shaandhada uu leeyahay shaandheyn hooseeysa, biin kasta wuxuu si wax ku ool ah u shaandheyn karaa qaabka caadiga ah hadda.Intaa waxaa dheer, isku xirka korantada filtarka ayaa sidoo kale leh iswaafajin wanaagsan, cabbirkeeda interface iyo cabbirka qaabka iyo xiriiriyaha korantada caadiga ah oo isku mid ah, sidaas darteed, si toos ah ayaa loo beddeli karaa.
Intaa waxaa dheer, isticmaalka isku xirka korantada filtarka ayaa sidoo kale leh dhaqaale wanaagsan, taas oo inta badan sabab u ah isku xirka awoodda shaandhada kaliya wuxuu u baahan yahay in lagu rakibo dekedda kiiska gaashaanka ah.Ka dib marka ay meesha ka saarto faragelinta hadda ee fiilada, kirishbooyuhu ma dareemi doono calaamadda faragelinta, sidaas darteed waxay leedahay waxqabad ka xasilloon marka loo eego fiilada gaashaanka ah.Xidhiidhiyaha korantada ee shaandhada ma laha shuruudo sare oo loogu talagalay xidhiidhka dhamaadka fiilada, markaa uma baahna in la isticmaalo fiilada tayada sare leh oo dhan, taas oo sii muujinaysa dhaqaalaheeda wanaagsan.
