Igebengu likaMazibuthe linezici ezihlukene zokuvimba kumafrikhwensi ahlukene. Ngokuvamile, i-impedance incane kakhulu kumafrikhwensi aphansi, futhi i-impedance ikhuphuka kakhulu kumafrikhwensi aphezulu. Lapho imvamisa yesignali iphezulu, kuba lula ukuthi inkambu kazibuthe iphume. Ngokuvamile, imigqa yesignali ayivikelwe. Isibonelo, ibhasi le-CAN engilisebenzisa manje. Le migqa yesignali iba izinti. Le antenna ithola ngokuqhubekayo amasiginali azungeze imvamisa ephezulu. I-Superposition ishintsha isignali yangempela ukuze idluliselwe. Indandatho kazibuthe ingadlulisa amasiginali awusizo ngenkathi icindezela amasiginali wokuphazamiseka wemvamisa ephezulu.
Kububanzi befrikhwensi ephezulu, i-inductive reactance ihlala incane, kuyilapho i-impedance inkulu, ukuze kuthi lapho amandla esiginali yefrikhwensi ephezulu edlula ezintweni kazibuthe, aguqulelwe ekushiseni futhi akhishwe, okuvimbela ukudlula kokuphezulu. -isignali yefrikhwensi futhi icindezela ukuphazanyiswa kwesignali ye-high-frequency. . Ngokuvamile uhla lokuvama kokucindezelwa luhlobene nesici sokucindezela i-ferrite. Ngokuvamile, ukuphakama kwamandla kazibuthe, imvamisa yokucindezela iyancipha. Uma umkhulu umthamo we-ferrite, ungcono umphumela wokucindezela. Uma ivolumu ingashintshi, ubude futhi mncane kakhulu kunemifushane futhi iminyene. Umphumela wokucindezela muhle, amancane amandla angaphakathi, ngcono umphumela wokucindezela.
Uma ucindezela ukuphazamiseka kwesignali yemodi evamile, ungadlula isignali noma ulayini wamandla eringini kazibuthe eyisicaba ngesikhathi esifanayo. Ukuze ukhuphule umthelela, ungenza ukuphenduka okulingene okumbalwa kwendandatho kazibuthe ukuze ukhuphule i-inductance futhi uthuthukise umphumela wokumunca wesiginali yemodi evamile. Isignali embi ayinawo umphumela.
I-Huizhou Mingda Precise Electronics Co., Ltd. inomkhiqizi onguchwepheshe ekukhiqizeni izindandatho kazibuthe ze-EMI ezilwa nokuphazamiseka. Sinonjiniyela abaneminyaka engu-20 ye-TDK R&D kanye nesipiliyoni sokuklama. Singakwazi ukwenza ngokwezifiso izindandatho kazibuthe ngokusebenza okukhethekile nosayizi ngokuya ngezidingo ezihlukene zamakhasimende zamasongo kazibuthe e-EMI anti-interference. umkhiqizo.
