，并基于模型、小波頻譜分析，虛擬儀器儀器提供了特殊設(shè)計(jì)的信號處理工具的總和。這聲音和振動工具的總和提供了八度分析，平均的和非均勻的頻率分析，瞬態(tài)分析，加權(quán)濾波，和音平測量以及其他。DrawYourOwnSolutionWithLabview,youbuildgraphicalprogramscalledvirtualinstruments(Vls)insteadofwritingtext-basedprograms.Youquicklycreatefrontpaneluserinterfacesthatgiveyoutheinteractivecontrolofyoursystem.Toaddfunctionalitytotheuserinterface,youintuitivelyassembleblockdiagrams---anaturaldesignnotationforengineersandscientists.構(gòu)思自己的解決方案通過對虛擬儀器的使用，你創(chuàng)建了被稱為虛擬儀器(Vis)而不是寫文本程序的圖形化程序。你快速地創(chuàng)建面板，給你的用戶界面交互控制你的系統(tǒng)。為了去添加功能，用戶界面，你直覺地裝配框圖一一種使用于工程師和科學(xué)家的自然設(shè)計(jì)符號法。CreattheFrontPanelOnthefrontofyourVI,youplacethecontrolanddatadisplaysforyoursystembyselectingobjectsfromthecontrolspalette,suchasnumericdisplay,meters,gauges,LEDs,charts,andgraphs.WhenyoucompleteandrunyourVI,youusethefrontpaneltocontrolyoursystemwhetheryoumoveaslide,zoominonagraph,orenteravaluewiththekeyboard.創(chuàng)建前面板在你的虛擬儀器界面的前面板上，你通過選擇從控制對象調(diào)色板 ，比如數(shù)字顯示,儀表,儀表、指示燈、圖表和圖形來放置控件和數(shù)據(jù)顯示為你的系統(tǒng)。當(dāng)你完成并運(yùn)行你的虛擬儀器時(shí)你通過操作這前面板去控制你的系統(tǒng)是否移動了一張放大的圖片或者用鍵盤輸入了值。ConstructtheGraphicalBlockDiagramToprogramtheVI,youconstructtheblockdiagramwithoutworryingaboutthesyntacticaldetailsoftext-basedprogrammingIanguages.Youdothisbyselectingobjects(icons)fromtheFunctionspaletteandconnectingthemtogetherwithwirestotransferdataamongblockdiagramobjects.Theseobjectsincludesimplearithmeticfunctions,advaneedacquisitionandanalysisroutines,networkandfileI/Ooperations,andmore.構(gòu)建圖形框圖在虛擬儀器框圖上編程你構(gòu)建框圖，不用擔(dān)心它的基于文本的編程語言的句法細(xì)節(jié)。你通過從功能控制面板和連接在一起的導(dǎo)線之間傳輸數(shù)據(jù)框圖的對象來選擇對象(圖標(biāo))而完成構(gòu)建框圖。這些對象包括簡單的運(yùn)算功能 ，先進(jìn)的采集和分析程序、網(wǎng)絡(luò)和文件I/O操作等等。DataflowProgrammingLabviewusesapatenteddataflowprogrammingmodelthatfreesyoufromthelineararchitectureoftext-basedprogramminglanguages.BecausetheexecutionorderinLabviewisdeterminedbytheflowofdatabetweennodes,andnotbysequentiallinesoftext,youcancreateblockdiagramsthatexecutemultipleoperationsinparallel.consequently,LabviewisamultitaskingsystemcapableofrunningmultipleexecutionthreadsandmultipleVIsinparallel.數(shù)據(jù)流編程虛擬儀器使用一種專利數(shù)據(jù)流規(guī)劃模型來釋放你的基于文本的編程語言的線性結(jié)構(gòu)。由于執(zhí)行命令的數(shù)據(jù)是由節(jié)點(diǎn)之間的數(shù)據(jù)流,而不是按序貫行文本，你可以創(chuàng)建執(zhí)行并行多重操作的框圖。因此虛擬儀器是一種在并行方式下有能力執(zhí)行多重執(zhí)行線程和多重虛擬儀器可見的多重任務(wù)系統(tǒng)。ModularityandHierarchyLabviewVIsaremodularindesign,soanyVIcanbyitselforaspartofanotherVI.YoucanevencreateiconsforyourownVIs,soyoucandesignahierarchyofVIsandsubVIsthatserveasapplicationbuildingblocks.Youcanmodify,interchange,andcombinethemwithotherVIstomeetyourchangingapplicationneeds.模塊化和層次結(jié)構(gòu)虛擬儀器可見化是一種模塊化設(shè)計(jì)，因此一些虛擬儀器可見可以是虛擬儀器本身或者作為虛擬儀器的其中一部分。所以你可以設(shè)計(jì)VIs和subVIs的層次來作為應(yīng)用程序構(gòu)造模塊。你可以修改、互換、和其他VIs結(jié)合來滿足你不斷改變的應(yīng)用程序的需要。GraphicalCompilerInmanyapplications,executionspeediscritical.Labviewistheonlygraphicalprogrammingsystemwithacompilerthatgeneratesoptimizedcodewithexecutionspeedscomparabletocompiledprograms.YoucanevenusetheLabviewprofilertoanalyzeandoptimizetime-criticaloperations.Consequently,youincreaseyourproductivitywithgraphicalprogrammingwithoutsacrificingexecutionspeed.圖形編輯器在許多應(yīng)用程序軟件中，執(zhí)行速度是很重要的。虛擬儀器是唯一的一個(gè)產(chǎn)生其優(yōu)化速度可比得上編程程序的編譯器的圖形化編程系統(tǒng)。你甚至可以運(yùn)用虛擬儀器分析器去分析和優(yōu)化時(shí)間至上的操作。結(jié)果，你在沒有以犧牲運(yùn)行速度的圖形化編程的前提下提高了你的運(yùn)行效率。MeasurementsandMathematicsLabviewincludesavarietyofothermeasurementanalysistools.Examplesincludecurvefitting,signalgeneration,peakdetection,andprobabilityandstatistics.MeasurementanalysisfunctionscandeterminesignalcharacteristicssuchasDC/RMSlevels,totalharmonicdistortion(THD),impulseresponse,frequencyresponse,andcross-powerspectrum.Labviewuserscanalsodeploynumericaltoolsforsolvingdifferentialequations,optimization,rootfinding,andothermathematicalproblem.Inaddition,youcanextendthesebuilt-incapabilitiesbyenteringMatlaborHIQscriptsdirectlyinyourLabviewprograms.Forchartingandgraphing,youcanrelyonthebuilt-inLabview2Dand3Dvisualizationtools.2DtoolsincludefeaturessuchasautoscalingXandYranges,reconfigurableattributes(point/linestyles,colors,andmore)andcursors.MicrosoftWindowsuserscanemployOpenGL-based3Dgraphsandthendynamicallyrotate,zoom,andpanthesegraphswiththemouse.測量與數(shù)學(xué)虛擬儀器包含了許多其他的測量分析工具。例子包括曲線擬合信號的生成、峰值檢測，概率和統(tǒng)計(jì)測量分析功能可以確定信號的特點(diǎn)，例如 DC/RMS水平，總諧波失真(THD，脈沖響應(yīng)，頻率響應(yīng)，互功率譜。虛擬儀器的用戶也可以部署數(shù)值工具，優(yōu)化,解決微分方程根的發(fā)現(xiàn)，和其他的相關(guān)的數(shù)學(xué)問題。另外你也可以在你的虛擬儀器程序中通過直接進(jìn)入 Matlab后者HIQ原稿來延長這些內(nèi)置的能力。為了制圖和繪圖，你可以依靠這內(nèi)置的虛擬儀器 2D和3D的可視化工具。2D工具包含的特征功能有如自動縮放X和丫的范圍、可重構(gòu)屬性(點(diǎn)、線款式、色彩，以及更多)和游標(biāo)。MicrosoftWindows用戶能夠使用基于OpenGL的3D圖形，然后動態(tài)縮放、旋轉(zhuǎn)、和用鼠標(biāo)移動這些圖。ComplexMeasurementsMadeEasyDespitethecomplexityoftheunderlyingalgorithmsthatimplementthesefunctions,youwillfindthemeasytouse.Forexample,asetofbuilt-inmeasurementfunctionsusesthenewwaveformdatatypetoacceptre—world,time—domainsignalinputsdirectlyfromDAQhardwareandreportresultsreadyforcharting,graphing,orthenextstageofsignalprocessing.復(fù)雜測量的簡化盡管實(shí)現(xiàn)這些基本功能算法的復(fù)雜性，你會發(fā)現(xiàn)它們是易于使用的。例如
