LC yakaderera-pass mafirita inoita basa rakakosha mumagetsi masaini kugadzirisa. Ivo vanogona kunyatsosefa yakaderera-frequency masiginecha uye kudzvinyirira yakakwira-frequency ruzha, nekudaro vachivandudza kunaka kwemasaini. Inoshandisa synergy pakati inductance (L) uye capacitance (C). Inductance inoshandiswa kudzivirira kudarika kwe-high-frequency signals, nepo capacitance inotumira uye inosimudzira zviratidzo zvishoma-frequency. Iyi dhizaini inoita kuti LC yakaderera-pass mafirita iite basa rakakosha mune akawanda emagetsi masisitimu, kunyanya mukuvandudza mhando yechiratidzo uye kuderedza ruzha.
Nekuvandudzwa kwesainzi uye tekinoroji, kudiwa kwemasaini emhando yepamusoro muminda yakaita sewaya yekutaurirana, kugadzirwa kweaudio, uye kutapurirana kwemifananidzo kuri kukura. Sechikamu chakakosha chekugadzirisa zviratidzo, LC yakaderera-pass mafirita ane tarisiro yakakura yekushandisa mune idzi minda. Mune mawaya ekukurukurirana masisitimu, LC yakaderera-pass mafirita anogona kunyatsosefa yakakwirira-frequency masaini masaini uye anovandudza chiratidzo chechiratidzo pamagumo ekugamuchira; pamagumo ekutumira, inogona zvakare kuve nechokwadi chekuteerera kwechiratidzo bandwidth uye kudzivirira kukanganiswa nemamwe ma frequency band. Mumunda wekugadzirisa odhiyo, LC yakaderera-pass mafirita anobatsira kubvisa yakakwirira-frequency ruzha uye anorasika masaini mumasaini masaini, achipa akajeka uye akachena maodhiyo maitiro. Kunyanya mumaodhiyo masisitimu, mafirita akakosha pakuvandudza ruzha rwemhando. Panyaya yekugadziriswa kwemifananidzo, iyo LC yakaderera-pass sefa inoderedza yakakwira-frequency ruzha mumufananidzo, inodzvanya kukanganisa kwemavara, uye inova nechokwadi chekuti chifananidzo chakajeka uye chakanyanya kuitika.
Iwo makuru maficha eLC yakaderera-pass sefa anosanganisira yakatsetseka frequency mhinduro uye yakanaka chikamu mutsara. Pazasi peiyo cutoff frequency, iyo chiratidzo attenuation idiki, ichivimbisa kutendeseka kwechiratidzo; pamusoro peiyo cutoff frequency, chiratidzo chekudzikisira chakakwira, ichinyatso kusefa kunze kwepamusoro-frequency ruzha. Uye zvakare, mutsara wechikamu chayo unovimbisa kuti chiratidzo chinogona kuchengetedza hukama hwayo hwepakutanga mushure mekusefa, izvo zvinonyanya kukosha kune maapplication akadai sedhidhiyo kugadzirisa uye kutapurirana kwemifananidzo.
Nekufambira mberi kwetekinoroji, iyo LC yakaderera-pass sefa ichaenderera mberi nekuvandudza uye kusimudzira munzira yeminiaturization, kusanganisa, uye yakakwirira-frequency application, ichiwedzera kuwedzera nzvimbo dzayo dzekushandisa. Mune ramangwana, LC yakaderera-pass mafirita ichaita basa rakakura mune mamwe emagetsi masisitimu, kusimudzira budiriro yesainzi uye tekinoroji uye kufambira mberi kweindasitiri.
