Izihluzi

Isihluzo sinokucoca ngempumelelo i-frequency ye-frequency ethile kwintambo yamandla okanye i-frequency engeyiyo indawo ye-frequency, sifumane isignali yomthombo wamandla ye-frequency ethile, okanye sisuse isignali yamandla ye-frequency ethile.

 

Intshayelelo

Isihluzo sisixhobo sokukhetha esivumela ukuba icandelo elithile lefrikhwensi kwisignali lidluliswe, kwaye ezinye iinxalenye zefrikhwensi zincitshiswe kakhulu. Esi siphumo sokukhetha sisebenzisa isihluzo sinokuhluzwa kwingxolo yokuphazamiseka okanye senze uhlalutyo lwe-spectrum. Ngamanye amazwi, sibizwa ngokuba sisihluzo esinokubangela ukuba icandelo elithile lefrikhwensi kwisignali lidlule, kwaye sincitshiswe kakhulu okanye sicinezele ezinye iinxalenye zefrikhwensi. Isihluzo sisixhobo esihluzwa yi-wave. "I-Wave" yingcamango ebanzi kakhulu yomzimba, kwicandelo lobuchwepheshe be-elektroniki, "i-wave" inqunyelwe kancinci kwinkqubo yokukhupha ixabiso leenani ezahlukeneyo zomzimba ngokuhamba kwexesha. Inkqubo iguqulwa ibe ngumsebenzi wexesha we-voltage okanye umbane ngokusebenzisa iindidi ezahlukeneyo zobuninzi bomzimba, okanye imiqondiso. Ekubeni ixesha eliguquguqukayo lixabiso eliqhubekayo, libizwa ngokuba yisignali yexesha eliqhubekayo, kwaye ngokwesiko libizwa ngokuba yisignali yexesha eliqhubekayo, kwaye ngokwesiko libizwa ngokuba yisignali ye-analog.

Ukucoca yingcamango ebalulekileyo ekucutshungulweni kwesignali, kwaye umsebenzi wesekethe yokucoca kwi-DC voltage regulator kukunciphisa i-AC component kwi-DC voltage kangangoko kunokwenzeka, ukugcina isithako sayo se-DC, ukuze i-output voltage ripple coefficient yehle, i-waveform ibe yi-Smooth.

Tiiparameter eziphambili:

Ifrikhwensi esembindini: Ifrikhwensi f0 yebhanti yokudlula yesihluzo, ngokubanzi ithatha i-f0 = (f1 + f2) / 2, f1, f2 njengebhanti yokudlula okanye isihluzo sokumelana nebhanti ekhohlo, ngasekunene ecaleni kwe-1 dB okanye i-3DB edge frequency point. Isihluzo sebhanti enqamlezileyo sidla ngokubala i-bandwidth yebhanti yokudlula kunye nenqaku elincinci lokulahleka kokufakwa.

Umhla wokugqibela: Ibhekisa kwindlela eya kwindlela ye-passband yesihluzi se-low pass kunye ne-passband yesihluzi se-high pass. Idla ngokuchazwa kwindawo yokulahleka okulinganiselweyo ye-1 dB okanye i-3DB. I-reference reference reference reference relative loss yile: i-low pass isekelwe kwi-DC insertion, kwaye i-Qualcomm isekelwe kwi-high-pass frequency eyaneleyo ye-parasitic strip.

Ibhendi yokudlula: ibhekisa kububanzi be-spectrum obufunekayo ukuze kudlule, BW = (F2-F1). F1, F2 isekelwe ekulahlekelweni kokufakwa kwisangqa esiphakathi F0.

Ukulahleka kokufakwa: Ngenxa yokungeniswa kwesihluzo emoyeni wesignali yokuqala kwisekethe, ilahleko embindini okanye kumaza okunqunyulwa, njengoko kufuneka ukuze kubekho ilahleko yebhendi yonke ukuze igxininiswe.

I-Ripple: Ibhekisa kuluhlu lwe-bandwidth ye-1DB okanye ye-3DB (i-cutoff frequency), i-insert loss itshintsha incopho ye-frequency kwi-loss mean curve.

Ukuguquguquka kwangaphakathi: Ukulahleka kokufakwa kwibhendi ye-through kunye notshintsho lwefrikhwensi. Ukuguquguquka kwebhendi kwi-bandwidth ye-1db yi-1db.

Ukulinda okungaphakathi kwebhendi: Linganisa ukuba isignali ekwi-passband kwisihluzo ilungile na ukuze ihambelane nokudluliselwa kokudluliselwa. I-Ideal Match VSWR = 1: 1, i-VSWR inkulu kune-1 xa ingangqinelani. Kwisihluzo sokwenyani, i-bandwidth eyanelisa i-VSWR ingaphantsi kwe-1.5: 1 ngokubanzi ingaphantsi kwe-BW3DB, echaza umlinganiselo we-BW3DB kunye nomyalelo wesihluzo kunye nokulahleka kokufakwa.

Ukulahleka kwendonga: Inani lee-decibels (DB) ratios zamandla okufaka isignali yezibuko kunye namandla abonakalisiweyo lilingana ne-20 Log 10ρ, i-ρ yi-voltage reflection coefficient. Ilahleko yokubuya ayinasiphelo xa amandla okufaka efunxwa yizibuko.

Ukuveliswa kwakhona koxinzelelo lwe-strip: isalathisi esibalulekileyo somgangatho wokusebenza kokukhetha isihluzo. Okukhona isalathisi siphezulu, kokukhona ukucinezelwa kwesignali yokuphazamiseka kwangaphandle kungcono. Kukho iintlobo ezimbini zesiphakamiso: indlela yokucinezela ukuba ingakanani i-DB inhibition ye-band crossing frequency fs, indlela yokubala yi-FS decrease; esinye isibonakaliso sesiphakamiso se-symbol filter threading kunye nendlela efanelekileyo ye-rectangle - i-Rectangular coefficient (i-KXDB inkulu kune-1), i-KXDB = i-BWXDB / i-BW3DB, (i-X ingaba yi-40dB, i-30dB, i-20DB, njl.njl.). Okukhona ii-rectangles zininzi, kokukhona i-rectangleity iphezulu - oko kukuthi, isondele kwixabiso elifanelekileyo i-1, kwaye ubunzima bokwenza imveliso bukhulu ngokuqinisekileyo.

Ukulibaziseka: Isignali ibhekisa kwixesha elifunekayo ukuze isignali idlulise i-phase function diagonal frequency, oko kukuthi, i-TD = DF / DV.

Ulungelelwaniso lwesigaba esingaphakathi kwebhendi: Esi sihluzo sophawu lwesalathisi sisiphumo sokuphambuka kwesigaba somqondiso odluliselweyo kwi-passband. Isihluzo esiyilwe ngumsebenzi wempendulo yesigaba esithe ngqo sinomgca othe ngqo wesigaba olungileyo.

Udidi oluphambili

Yahlulwe yaba sisihluzo se-analog kunye nesihluzo sedijithali ngokwesiginali esicutshungulwayo.

Indlela yokudlula kwesihluzo esingasebenziyo yahlulwe yaba yi-low pass, high pass, bandpass, kunye ne-all-pass filter.

Isihluzi sokudlula okuphantsi:ivumela ukuba kudluliswe izinto ezisebenzisa i-low-frequency okanye i-DC kwisignali, icinezele izinto ezisebenzisa i-high frequency okanye ukuphazamiseka kunye nengxolo;

Isihluzi esidlula phezulu: ivumela ukuba kudluliswe izinto ezisebenzisa i-frequency ephezulu kwisignali, kucinezelwe izinto ezisebenzisa i-frequency ephantsi okanye i-DC;

Isihluzi seBand Pass: Ivumela ukuba imiqondiso idluliselwe, icinezelwe imiqondiso, ukuphazamiseka, kunye nengxolo engaphantsi okanye ngaphezulu kwebhendi;

Isihluzi esinokubopha: Icinezela imiqondiso ngaphakathi kwebhendi ethile yefrikhwensi ivumela imiqondiso engeyiyo ibhendi, eyaziwa ngokuba sisihluzi senotshi.

Isihluzi se-All-pass: Isihluzi se-full-pass sithetha ukuba i-amplitude yesignali ayizukutshintsha ngaphakathi koluhlu olupheleleyo, oko kukuthi, i-amplitude gain yoluhlu olupheleleyo ilingana ne-1. Ii-general all-pass filters zisetyenziselwa isigaba sesigaba, oko kukuthi, isigaba sotshintsho lwesignali yokufaka, kwaye eyona nto ifanelekileyo kukuba utshintsho lwesigaba luhambelane ne-frequency, elingana nenkqubo yokulibaziseka kwexesha.

Zombini izinto ezisetyenzisiweyo zizihluzi ezingasebenziyo nezisebenzayo.

Ngokuxhomekeke kwindawo ebekwe kuyo isihluzo, ngokubanzi sahlulwe saba sisihluzo sepleyiti kunye nesihluzo sephaneli.

Ebhodini, faka ebhodini, njenge-PLB, isihluzi sochungechunge lwe-JLB. Iingenelo zesi sihluzi zingabizi kakhulu, kwaye ingxaki kukuba ukucoca rhoqo akukuhle. Isizathu saso esiphambili sesi:

1. Akukho kwahlukana phakathi kokufakwa kunye nokuphuma kwesihluzi, esinokuxhomekeka ekudibaneni;

2, i-grounding impedance ye-filter ayiphantsi kakhulu, yenza buthathaka isiphumo se-high frequency bypass;

3, iqhekeza lonxibelelwano phakathi kwesihluzo kunye ne-chassis liya kuvelisa iziphumo ezimbini ezimbi: enye kukuphazamiseka kwe-electromagnetic kwendawo yangaphakathi ye-chassis, ebangelwa ngqo kulo mgca, ecaleni kwentambo, kwaye ikhuphe isihluzo ngokusebenzisa imitha yekhebula. Ukusilela; enye kukuba ukuphazamiseka kwangaphandle kuhluzwa sisihluzo sesihluzo ebhodini, okanye imitha iveliswa ngokuthe ngqo okanye ngokuthe ngqo kwisekethe kwibhodi yesekethe, nto leyo ebangela iingxaki zovakalelo;

Iipleyiti zezixhobo zokucoca, izihlanganisi zezixhobo zokucoca kunye nezinye izixhobo zokucoca iiphaneli zihlala zifakelwe kwiphaneli yesinyithi ye-chassis yokukhusela. Ekubeni ifakwe ngqo kwiphaneli yesinyithi, igalelo kunye nesiphumo sesixhobo sokucoca zihlukaniswe ngokupheleleyo, umhlaba usekelwe kakuhle, kwaye ukuphazamiseka kwintambo kuhluzwa phezu kwesango le-chassis, ngoko ke isiphumo sokucoca sifanelekile.

Isihluzi esingasebenziyo

Isihluzo esingasebenziyo sisixhobo sokucoca esisebenzisa i-resistor, i-reactor, kunye ne-capacitor component. Xa i-resonant frequency, ixabiso le-circuit impedance lincinci, kwaye i-circuit impedance inkulu, ixabiso le-circuit component lihlengahlengiswa kwi-feature harmonic frequency, kwaye i-harmonic current inokuhluzwa; xa ii-harmonic frequenses ezininzi I-tuning circuit yenziwe, emva koko i-feature harmonic frequency ehambelanayo inokuhluzwa, kwaye ukuhluza i-harmonic number main (3, 5, 7) kufezekiswa nge-low impedance bypass. Umgaqo oyintloko kukuba inani elahlukileyo le-harmonics, ukuyila i-harmonic frequency kuncinci, kufezekisa isiphumo sokuqhekeka kwe-harmonic current, kubonelela nge-bypass passage ye-harmonic ephezulu ehluziweyo kwangaphambili ukuze kufezekiswe i-waveform yokuhlanjululwa.

Izihluzi ezingasebenziyo zinokwahlulwa zibe zizihluzi ezikwaziyo ukuthwala amandla, izihluzi zezityalo zamandla, izihluzi ze-L-RC, izihluzi ze-RC ezimile okwe-π, izihluzi ze-RC ezimile okwe-multi-section, kunye nezihluzi ze-LC ezimile okwe-π. Cinezela ukuze usebenze kwisihluzi esinye sokulungisa, isihluzi sokulungisa esiphindwe kabini, kunye nesihluzi esidlula phezulu. Isihluzi esingasebenziyo sinezi nzuzo zilandelayo: isakhiwo silula, iindleko zotyalo-mali ziphantsi, kwaye icandelo elisebenzayo kwinkqubo linokuhlawula amandla kwinkqubo. Liphucula amandla egridi; uzinzo lokusebenza luphezulu, ukugcinwa kulula, ukuvuthwa kobugcisa, njl. Isetyenziswa kakhulu. Kukho iinkalo ezininzi zeziphene zezihluzi ezingasebenziyo: impembelelo yeeparamitha zegridi yamandla, ixabiso le-impedance yenkqubo kunye nenani eliphambili leefrikhwensi ze-resonant zihlala zitshintsha njengoko iimeko zokusebenza zitshintsha; isihluzi se-harmonic sincinci, kuphela inani eliphambili lamaxesha aphambili elinokuhluzwa kuphela kwiHarmonics, okanye ngenxa yeentsalela ezifanayo, ukukhulisa iiharmonics; ulungelelwaniso phakathi kokucoca kunye nokuhlawula okusebenzayo kunye nokulawula uxinzelelo; njengoko umbane uhamba ngesihluzi, unokubangela ukusebenza okugqithisileyo kwezixhobo; Izinto ezisetyenziswayo zikhulu kakhulu, ubunzima kunye nomthamo mkhulu; uzinzo lokusebenza alulunganga. Ke ngoko, isihluzo esisebenzayo esisebenza ngcono sisetyenziswa kakhulu.
