“林奎茨电路”均衡封闭箱

摘要：林奎茨均衡，意为极复杂的系统，其中q>0.5，中和原零极点补偿，然后创建一个新的高通响应由设计师指定的原始响应。原来的一样，新的电路提供了一个2阶响应。Maxim>AppNotes>AudioCircuitsKeywords:equalizers,low-noiselow-distortionopamps,low-frequencyloudspeakers,bassresponseDec21,2010APPLICATIONNOTE4525"LinkwitzCircuit"EqualizesaClosedBoxAbstract:TheLinkwitzequalizer,intendedforcomplex-polesystemsinwhichQ>0.5,neutralizestheoriginalresponsebycompensatingtheoriginalpoleswithzeros,andthencreatesanewhighpassresponseasspecifiedbythedesigner.Liketheoriginal,thenewcircuitprovidesa2nd-orderresponse.AsimilarversionofthisarticleappearedintheMay6,2008issueofEETimesmagazine.Thelinearityandhighpower-handlingcapabilityofmodernlow-frequencyloudspeakershavemadeiteasytoelectronicallyextendthebassresponse.Thisextensionises
