Basa rakakosha remafirita eLC low-pass mumasisitimu emagetsi emazuva ano

Mafirita eLC low-pass anoita basa rakakosha mukugadzirisa masaini emagetsi. Anogona kusefa masaini ane frequency yakaderera uye kudzvinyirira ruzha rwehigh-frequency, nokudaro achivandudza mhando yemasaini. Anoshandisa kubatana pakati peinductance (L) necapacitance (C). Inductance inoshandiswa kudzivirira kupfuura kwemasaini ane frequency yakakwirira, ukuwo capacitance ichitumira uye ichikwidziridza masaini ane frequency yakaderera. Dhizaini iyi inoita kuti mafirita eLC low-pass aite basa guru mumasisitimu akawanda emagetsi, kunyanya mukuvandudza kunaka kwemasaini uye kuderedza ruzha.

Nekuvandudzwa kwesainzi netekinoroji, kudiwa kwemasaini emhando yepamusoro muminda yakadai sekutaurirana pasina waya, kugadzirisa manzwi, uye kutumira mifananidzo kuri kukura. Sechikamu chakakosha chekugadzirisa masaini, mafirita eLC low-pass ane mikana yakawanda yekushandisa muminda iyi. Mumasisitimu ekutaurirana asina waya, mafirita eLC low-pass anogona kusefa masaini ehigh-frequency interference uye kuvandudza mhando yesignal padivi rinogashira; padivi rinotumira, rinogonawo kuve nechokwadi chekuti bandwidth yesignal inoenderana uye kudzivirira kukanganiswa nemamwe mabhendi emafrequency. Muminda yekugadzirisa manzwi, mafirita eLC low-pass anobatsira kubvisa ruzha rwehigh-frequency uye masaini akarasika muzviratidzo zveaudio, zvichipa mhedzisiro yeaudio yakajeka uye yakachena. Kunyanya mumasisitimu eaudio, mafirita akakosha pakuvandudza mhando yeruzha. Panyaya yekugadzirisa mifananidzo, firita yeLC low-pass inoderedza ruzha rwehigh-frequency mumufananidzo, inodzvinyirira kukanganisa kwemavara, uye inoita kuti mufananidzo uve wakajeka uye wechokwadi.

Zvinhu zvikuru zveLC low-pass filter zvinosanganisira kupindura kwema frequency akatsetseka uye kurongeka kwechikamu. Pasi pe cutoff frequency, kuderera kwechiratidzo kudiki, zvichiita kuti chiratidzo chive chakasimba; pamusoro pe cutoff frequency, kuderera kwechiratidzo kwakadzika, zvichinyatso bvisa ruzha rwe high-frequency. Pamusoro pezvo, kurongeka kwayo kwechikamu kunoita kuti chiratidzo chigone kuchengetedza hukama hwayo hwepakutanga mushure mekusefa, izvo zvinonyanya kukosha kumashandisirwo akadai sekugadzirisa odhiyo uye kutumira mifananidzo.

Nekufambira mberi kwetekinoroji, firita reLC low-pass richaramba richivandudza nekuvandudza nzira ye miniaturization, kubatanidzwa, uye mashandisirwo e high-frequency, zvichiwedzera kuwedzera nzvimbo dzaro dzekushandisa. Mune ramangwana, mafirita eLC low-pass achaita basa guru muhurongwa hwemagetsi, zvichikurudzira kukura kwesainzi netekinoroji uye kufambira mberi kweindasitiri.
