Amakuru

Akayunguruzo, bizwi kandi nka LC muyunguruzi, ni akayunguruzo k'umuzunguruko kagizwe na inductance, capacitance na resistance, zishobora gushungura kimwe cyangwa byinshi bihuza. Bikunze kugaragara kandi byoroshye gukoresha pasiporo yungurura ni uguhuza inductance na capacitance murukurikirane, rushobora gukora inzitizi ntoya yo guhuza ibice byingenzi (3, 5 na 7); Akayunguruzo kamwe kamwe, kuringaniza kabiri kayunguruzo hamwe na pass yo hejuru ya filteri byose ni passiyeri.
akarusho
Akayunguruzo ka pasiporo gafite ibyiza byuburyo bworoshye, igiciro gito, ibikorwa byinshi byizewe nigiciro gito cyibikorwa. Iracyakoreshwa cyane nkuburyo bwo kugenzura guhuza.
gushyira mu byiciro
Ibiranga LC muyunguruzi igomba kuba yujuje ibyangombwa bisabwa bya tekiniki. Ibi bisabwa bya tekiniki mubisanzwe bikora attenuation muri domaine yumurongo, cyangwa guhinduranya icyiciro, cyangwa byombi; Rimwe na rimwe, ibisabwa byo gusubiza mugihe cyateganijwe birasabwa. Akayunguruzo ka pasiporo gashobora kugabanywamo ibyiciro bibiri: byungurujwe muyunguruzi hamwe na pass yo hejuru. Igihe kimwe, ukurikije uburyo butandukanye bwo gushushanya, irashobora kugabanywamo ibice byerekana amashusho hamwe nakazi kayunguruzo.
Kurungurura
Akayunguruzo karimo akayunguruzo kamwe kamwe kayunguruzo hamwe na kabiri yo guhuza akayunguruzo, gashobora gushungura imwe (guhuza imwe) cyangwa bibiri (guhuza kabiri) guhuza. Inshuro zihuza byitwa resonant frequency ya tuning ya filteri.
Akayunguruzo keza
Akayunguruzo keza cyane, kazwi kandi nka amplitude yo kugabanya akayunguruzo, cyane cyane karimo urwego rwa mbere rwo hejuru rwunguruzo rwunguruzo, urwego rwa kabiri rwo hejuru rwunguruzo rwunguruzi, urwego rwa gatatu rwo hejuru rwunguruzo rwungurura na C-rwunguruzo, rukoreshwa muguhuza cyane guhuza ibice biri munsi yumurongo runaka, ibyo byitwa guca inshuro yumurongo wo hejuru.
Ishusho Ibishusho
Akayunguruzo kateguwe kandi gashyirwa mu bikorwa hashingiwe ku nyigisho y'ibipimo by'ishusho. Akayunguruzo kagizwe nibice byinshi byibanze (cyangwa igice cyigice) byashizwe kumurongo ukurikije ihame ryingingo zingana kubihuza. Igice cyibanze gishobora kugabanywa muburyo bwa K-bwoko na m-biva muburyo bwimiterere. Gufata LC ntoya-yungurura akayunguruzo nkurugero, guhagarika umurongo wa K-wateganijwe K-wo hasi-pass-shingiro igice cyiyongera kimwe hamwe no kwiyongera kwinshuro; M-ikomoka hasi-pass yibanze shingiro ifite impinga ya attenuation kuri frequence runaka muguhagarara, kandi umwanya wimpinga ya attenuation igenzurwa nagaciro ka m muri m-inkomoko. Kubyoroheje-byunguruzo bigizwe na Cascaded Hasi-Pass ibice byibanze, ibyiyumvo byihariye bihwanye nigiteranyo cyimiterere yihariye ya buri gice cyibanze. Iyo impedance yimbere hamwe nuburemere bwumuriro wamashanyarazi warangiye kumpande zombi ziyungurura bingana nimbogamizi kumashusho kumpande zombi, gukora attenuation no guhinduranya icyiciro cya filteri bingana no kwiyegereza kwabo hamwe no guhinduranya icyiciro. (a) Akayunguruzo kerekanwe kagizwe na K ihamye hamwe na m ebyiri zikomoka muri casade. Z π na Z π m nibishusho bibangamira. (b) Nibihe bya attenuation inshuro ziranga. Imyanya yimpande ebyiri zo hejuru / f ∞ 1 na f ∞ 2 mumurongo uhagarara bigenwa na m agaciro ka m ebyiri zikomoka kuri node.
Mu buryo busa nabwo, pass ndende, band-pass hamwe na bande ihagarika muyunguruzi irashobora kandi kuba igizwe nibice by'ibanze bihuye.
Ishusho ibangamira akayunguruzo ntishobora kuba ingana nimbaraga zo kurwanya imbere yimbere yumuriro wamashanyarazi hamwe nuburemere bwumutwaro mugice cyose cyumurongo (itandukaniro ni ryinshi mumurongo uhagarara), kandi kwiyitirira no gukora byitandukaniro bitandukanye cyane mumihanda. Kugirango hamenyekane ibipimo ngenderwaho bya tekiniki, mubisanzwe birakenewe kubika intera ihagije ya attenuation marike no kongera ubugari bwa passband mugushushanya.
Gukoresha ibipimo byungurura
Akayunguruzo ntabwo kagizwe n'ibice by'ibanze byashizwemo, ariko ikoresha imikorere y'urusobekerane rushobora kugerwaho muburyo bwa R, l, C hamwe nibintu bya inductance kugirango ugereranye neza ibisobanuro bya tekiniki byayunguruzo, hanyuma ukamenya umuzunguruko uhuye nibikorwa byurusobe rwabonye. Ukurikije ibipimo bitandukanye byo kugereranya, imikorere y'urusobekerane irashobora kuboneka, kandi ubwoko butandukanye bwo kuyungurura burashobora kugerwaho. . Passband nimwe iringaniye cyane hafi ya zeru, kandi attenuation yiyongera monotonique iyo yegereye guhagarara. . Kwiyongera muri passband ihindagurika hagati ya zeru no hejuru, kandi ikiyongera monotonike muri banda. . (g) Nibiranga akayunguruzo gato-kayunguruzo kakozwe na; Kwiyongera muri passband ihindagurika muri amplitude ingana, kandi kwiyerekana muri guhagarara bihindagurika ukurikije kuzamuka no kugwa bisabwa nurutonde. (b) ,,
Inzira ndende, bande-pass hamwe na bande ihagarika muyunguruzi mubisanzwe biva muburyo buke bwo kuyungurura hakoreshejwe uburyo bwo guhindura inshuro.
Akayunguruzo gakora kayunguruzo kateguwe nuburyo bwoguhuza neza ukurikije ibisabwa byerekana ibipimo bya tekiniki, kandi birashobora kubona akayunguruzo kayunguruzo hamwe nibikorwa byiza nubukungu,
LC muyunguruzi biroroshye gukora, hasi mubiciro, ubugari muri bande ya frequency, kandi ikoreshwa cyane mubitumanaho, ibikoresho nibindi bice; Mugihe kimwe, ikoreshwa kenshi nkigishushanyo mbonera cyubwoko bwinshi bwiyungurura.

Turashobora kandi gutegekanya ibice bya rf bikurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
