Uhlolojikelele Lomkhiqizo

Izihlungi ze-Sichuan Keenlion Microwave Technology ziklanywe ngokusebenzisa izakhiwo ezizwakalayo ezine-Q ephezulu kakhulu futhi zilungele izinhlelo zokusebenza ezinebhande elincane, ezikhethekayo. Le miklamo ingahlinzeka ngama-bandwidth emincane njengo-1% ngokukhetha okuphezulu kakhulu nomsindo ophansi ophansi kakhulu. Ukulahlekelwa kokufaka okuphansi kuhlanganiswe nokubamba amandla okuhle kakhulu kuzenza zikufanelekele kahle isidlulisi nesiphetho sangaphambili somamukeli. Idizayini yesihlungi esithuthukisiwe nokwakhiwa kunika amandla ububanzi be-stopband ngaphezu kuka-3x imvamisa emaphakathi.

Izihlungi zomgodi we-Sichuan Keenlion Microwave Technology zifaka umhlangano okhethekile ovikelayo ukuze kunqandwe ukucushwa ngengozi okungadinga ukushintshwa okumba eqolo noma kubuyiselwe efekthri ukuze kulungiswe kabusha. Ukwenza imishini enembile kuvumela ukugcwaliseka kwezihlungi ze-cavity ezinezici zefomu elincane lezinhlelo zokusebenza lapho usayizi ubalulekile. Ukuphindaphinda okuhle kakhulu kuwo wonke amayunithi kufinyelelwa ngokushuna okunembayo nokulawula inqubo.

Iphrofayela Yenkampani

I-Sichuan Keenlion Microwave Technology Yasungulwa ngo-2004, iSichuan Keenlion Mircrowave techenology Co., Ltd. ingumkhiqizi ohamba phambili wezingxenye zePassive Mircrowave eSichuan Chengdu, eChina.

Isihlungi se-Lowpass singesinye sezingxenye zamagagasi ezingaphezulu kwe-RF, i-microwave ne-millimeter ehlinzekwa yi-Sichuan Keenlion Microwave Technology. Isihlungi sethu se-low pass singathengwa futhi sithunyelwe emhlabeni wonke ngosuku olufanayo njengezinye izingxenye zethu ze-RF ezisesitokweni.

Isihlungi sokudlula okuphansi:

setha iphoyinti lokuvama. Uma ifrikhwensi yesignali ingaphezu kwalesi simiso, ayikwazi ukudlula. Kumasignali edijithali, leli phuzu lefrikhwensi imvamisa yokunqanyulwa. Uma isizinda sefrikhwensi siphezulu kunalesi sinqamuleli esinqunyiwe, wonke amanani anikezwa njengo-0. Ngoba kule nqubo, wonke amasignali we-low-frequency ayadlula, kubizwa ngokuthi ukuhlunga kwe-low-pass filtering.

Isibonelo sesihlungi sokudlula okuphansi:

Umgoqo oqinile uyisihlungi sephasi eliphansi lamagagasi omsindo. Uma udlala umculo kwelinye igumbi, kulula ukuzwa i-bass yomculo, kodwa iningi le-treble liyahlungwa. Ngokufanayo, umculo onomsindo kakhulu emotweni eyodwa uzwakala njenge-bass beat kubantu kwenye imoto, ngoba ngalesi sikhathi, imoto evaliwe (kanye negebe lomoya) isebenza njengesihlungi se-low-pass futhi yenza buthaka yonke i-treble.

Izihlungi ze-electronic low-pass zisetshenziselwa ukushayela ama-subwoofers nezinye izinhlobo zezikhulisa-zwi futhi zivimbe ama-treble beats angakwazi ukuzisakaza ngempumelelo.

Izithutha zomsakazo zisebenzisa izihlungi ezinamaphasi aphansi ukuvimba ukukhishwa kwe-harmonic okungase kubangele ukuphazamiseka kokunye ukuxhumana.

Isihlukanisi se-DSL sisebenzisa izihlungi zokudlula okuphansi neziphezulu ukuze zihlukanise i-DSL namasiginali wamabhodwe abelana ngamapheya asontekile.

Izihlungi zokudlula okuphansi nazo zidlala indima ebalulekile ekucutshungulweni komsindo womculo we-elekthronikhi ohlanganiswe ama-analog synthesizer afana ne-Roland.

Isihlungi esikahle nesisebenzayo isihlungi se-low-pass singasusa ngokuphelele wonke amasiginali wefrikhwensi ngaphezu kwefrikhwensi yokunqanyulwa, namasignali angaphansi kwefrikhwensi yokusika angadlula engathintekile. Indawo yokuguqulwa yangempela ayisekho. Isihlungi esilungile sephasi eliphansi singatholwa ngendlela yezibalo (ngokwethiyori) siphindaphinda isignali ngomsebenzi ongunxande kusizinda samafrikhwensi. Njengendlela enomphumela ofanayo, ingatholakala futhi ngokushintshanisa nomsebenzi we-sinc esizindeni sesikhathi.

Nokho, isihlungi esinjalo asibonakali kusignali yangempela. Lokhu kungenxa yokuthi umsebenzi we-sinc uwumsebenzi ofinyelela kokungapheli. Ngakho-ke, isihlungi esinjalo sidinga ukubikezela ikusasa futhi sibe nayo yonke idatha esikhathini esidlule ukuze senze convolution. Lokhu kungenzeka kusignali yedijithali erekhodiwe ngaphambilini (uziro wengezwa ngemuva kwesiginali ukuze iphutha elihlungiwe eliwumphumela libe lincane kunephutha le-quantization) noma isignali yomjikelezo engapheli.

Izihlungi ezisebenzayo ezinhlelweni zesikhathi sangempela zilinganiselwa kusihlungi esifanele ngokubambezela isignali isikhathi esifushane ukuze “zibone” ingxenye encane yesikhathi esizayo, efakazelwe ngokushintsha kwesigaba. Uma kuphezulu ukunemba kokulinganisa, kulapho ukulibaziseka okudingekayo kube kude.

I-theorem yesampula ichaza indlela yokwakha kabusha isignali eqhubekayo kusukela kusampula yesiginali yedijithali kusetshenziswa isihlungi sephasi eliphansi kanye nefomula yokuhumusha ye-Nyquist Shannon. Iziguquli zangempela zedijithali ukuya kwe-analogi zisebenzisa izihlungi ezilinganiselwe.
