Shaandheeyayaasha xargaha soo noqnoqda ee soo noqnoqda waa aalado elektaroonik ah oo loogu talagalay in lagu oggolaado kaliya tiro gaar ah oo calaamadaha soo noqnoqda ee sarreeya si ay u dhex maraan iyaga oo hoos u dhigaya calaamadaha wareegyada ka baxsan xadkaas. filtarradan waxaa caadi ahaan loo adeegsadaa hababka isgaarsiinta, qalabka maqalka, iyo codsiyada kale ee elegtarooniga ah ee u baahan jawaab celin sax ah. Qormadan, waxaan ku baari doonaa astaamaha muhiimka ah ee filtarrada gudbinta soo noqnoqda ee tirada badan, oo ay ku jiraan jawaab-celintooda soo noqnoqoshada, bandwidth, iyo Q-factor.
Jawaabta Joogtada ah: Jawaabta soo noqnoqda ee shaandhada baasaska sare ee soo noqnoqda ayaa go'aamisa sida ay u yaraynayso calaamadaha wareegyada ka baxsan baaska iyo inta ay kor u qaadayso calaamadaha ku dhex jira baaska. Si fiican loo qaabeeyey filtarrada soo noqnoqda ee soo noqnoqoshada sare waxay yeelan doontaa kala-guur fiiqan oo u dhexeeya baasabka iyo xadhiga joogsiga, iyadoo ay ugu yar tahay xadhigga baaska. Qaabka qalooca jawaabta soo noqnoqda waxaa lagu go'aamiyaa naqshadeynta filtarka, waxaana lagu sifeyn karaa inta jeer ee xarunteeda iyo baaxaddeeda.
Bandwidth: Xadhkaha xadhkaha xadhkaha goos gooska sare ee soo noqnoqda waa inta jeer ee loo ogolyahay in ay dhex maraan shaandhada iyada oo yarayn yar. Sida caadiga ah waxaa lagu qeexaa farqiga u dhexeeya sare iyo hoose -3 dB soo noqnoqoshada, kuwaas oo inta jeer ee awoodda wax soo saarka shaandhada la dhimay 50% marka loo eego awoodda ugu badan ee baasaboorka. Baaxadda shaandhada baaska soo noqnoqda ee inta jeer ee sare waa halbeeg muhiim ah oo go'aamisa doorashadeeda iyo sida ugu wanaagsan ee ay u diidi karto calaamadaha aan loo baahnayn ee ka baxsan baaska.
Q-Factor: Q-factor-ka shaandhada sare ee soo noqnoqoshada band waa cabbirka xulashada ama fiiqnaanta jawaabta soo noqnoqda filtarka. Waxaa lagu qeexay sida saamiga inta jeer ee xarunta iyo bandwidth. Q-factor sare waxay u dhigantaa xajmigu cidhiidhi ah iyo jawaab celin fiiqan oo soo noqnoqota ah, halka Q-factor hoose ay u dhiganto xajmi ballaaran iyo jawaab celin tartiib tartiib ah. Q-factor-ka shaandhada baaska soo noqnoqda ee heerka sare waa halbeeg muhiim ah oo go'aamisa waxqabadkiisa diidmada calaamadaha aan loo baahnayn ee ka baxsan baaska.
Khasaare Gelid: Luminta galinta shaandhada sare ee soo noqnoqda ee soo noqnoqda waa qadarka yarayn calaamadaha ee dhaca marka calaamaduhu dhex maraan shaandhada. Caadi ahaan waxa lagu muujiyaa decibels waana cabirka inta shaandhada ay dhayaliso calaamadaha ku jira baaska. Si fiican loo qaabeeyey filtarrada baaska soo noqnoqda ee soo noqnoqoshada waa in ay lahaataa luminta ugu yar ee gelinta baasaska si looga fogaado hoos u dhigista tayada calaamadda.
Is-waafajinta Is-waafajinta: Is-barbar-dhigga impedance waa sifo muhiim ah oo ka mid ah filtarrada gudbinta band-ka soo noqnoqda ee sarreeya, gaar ahaan nidaamyada isgaarsiinta. Wax-soo-saarka iyo wax-soo-saarka shaandhada waa in lagu wanaajiyaa isha iyo culeyska culeyska si loo yareeyo milicsiga calaamadaha loona wanaajiyo wareejinta calaamadaha. Shaandheeyaha baaska soo noqnoqda ee soo noqnoqda ee si fiican u dhigma wuxuu yeelan doonaa luminta calaamadaha ugu yar iyo qallooca.
Gebogebadii, filtarrada baaska soo noqnoqda ee inta jeer ee sarreeya ayaa ah qaybaha muhiimka ah ee wareegyada elektiroonigga ah ee u baahan jawaab celin joogto ah oo sax ah. Sifooyinkooda muhiimka ah waxaa ka mid ah jawaab celintooda soo noqnoqoshada, bandwidth, Q-factor, luminta gelinta, iyo isbarbardhigga is-waafajinta. Si fiican loo qaabeeyey filtarrada soo noqnoqda ee soo noqnoqoshada sare waa in ay lahaataa jawaab celin soo noqnoqota oo fiiqan, bandwidth cidhiidhi ah, luminta ugu yar ee galinta, iyo isbarbardhigga u dhigma si loo hubiyo waxqabadka ugu fiican.
