Firita yeBhendi: Kuchinja Indasitiri yeMagetsi

Semugadziri anotungamira wezvemagetsi, tinodada nekuunza hunyanzvi hutsva mumhando yedu yezvigadzirwa - iyo Sefa yeBhendi (BPF). MaBPF zvinhu zvemagetsi zvisingashande zvakagadzirwa kuti zvibvumire kuti mamwe mafrequency apfuure, ukuwo zvichivharira mamwe. Muchinyorwa chino cheblog, tichaongorora kuti maBPF ari kushandiswa sei muindasitiri yemagetsi kugadzira zvigadzirwa zviri nani uye kusimudzira mashandiro.

Chii chinonzi Band Pass Filter?

Firita yeBand Pass rudzi rwefirita yemagetsi inobvumira kuti huwandu hwakati hwemafrequencies hupfuure nepakati pecircuit yayo. Firita iyi inodzvanya mafrequencies ese kunze kwebandwidth inodiwa, zvichiita kuti ive chishandiso chinoshanda chekugadzirisa masaini. Mashandisirwo eBPFs muIndasitiri yeMagetsiBPFs anoshandiswa mumaindasitiri akasiyana-siyana, anosanganisira kutaurirana, odhiyo nemavhidhiyo, uye zvishandiso zvekurapa.

Heano mashandisirwo akakosha eBPFs muindasitiri yezvemagetsi.

Kutaurirana pasina waya:Mafirita eBand Pass anowanzo batanidzwa mumasisitimu ekutaurirana asina waya, akadai semafoni, kuti arambe akasimba. MaBPF anonyanya kubatsira kana zvasvika pakudzivisa masaini ari kunze kwebhendi, izvo zvinogona kukonzera kukanganiswa uye kuderedza kunaka kwemasaini.

Odhiyo nevhidhiyo:MaFilter eBand Pass anoshandiswawo mumasisitimu eaudio kudzivirira mafrequency asingadewi kuti apfuure nepakati. Anogonesa kugadzirwa kweruzha rwemhando yepamusoro pasina ruzha kana kukanganiswa. Mukugadzirwa kwemavhidhiyo, maBPF ave kudiwa pakugadzirwa kweHD visuals. Anorerutsa kubviswa kwemafrequencies asingadiwe uye harmonics uku achichengetedza huwandu hwaunoda.

Zvishandiso zvekurapa:MaBPF ave zvinhu zvinodiwa mumidziyo yekurapa yakaita semagineti ekufungidzira (MRI). Nekudzikisa mafrequency ari kunze kwehuwandu hwaunoda, anogadzira mifananidzo yakajeka. Saizvozvowo, anoshandiswa mukuongorora ropa kusefa masero matsvuku nemachena eropa kubva mumuenzaniso.

Mukupedzisa, maFilter eBand Pass zvishandiso zvine simba zvinogona kusimudzira mashandiro emidziyo yemagetsi. Kugona kwavo kudzvinyirira mafrequency asingadiwe uye kuwedzera chiyero chesignal-to-noise kunoita kuti vabatsire mumabasa akasiyana-siyana.

Semugadziri anotungamira wezvemagetsi, tinodada nekubatanidza tekinoroji iyi muzvigadzirwa zvedu kuti tipe mashandiro emhando yepamusoro kune vatengi vedu. Kukosha kwayo mukusimudzira mashandiro emagetsi kunoita kuti Band Pass Filters ive chinhu chakakosha muindasitiri yezvemagetsi.

Microwave yeSi Chuan Keenlion sarudzo yakakura mu narrowband uye broadband configurations, inofukidza ma frequency kubva pa 0.5 kusvika 50 GHz. Yakagadzirwa kuti ishande simba rekupinda rema watts gumi kusvika makumi matatu mu 50-ohm transmission system. Madhizaini e microstrip kana stripline anoshandiswa, uye akagadziridzwa kuti ashande zvakanaka.

Tinogonawo gadzirisa Firita yeRF Band Pass zvinoenderana nezvaunoda. Unogona kupinda papeji rekugadzirisa kuti upe zvinodiwa zvaunoda.
