改变原始wav音频信号的抽样频率，并且显示处理前后声音信号的频谱.有助于帮助大家理解奈圭斯特抽样定理。-Change the original wav audio signal sampling frequency, and shows the spectrum of sound signal before and after treatment. Helps to help you understand the Nyquist sampling theorem.

本文阐述了研究背景，故障诊断技术的发展及其国内外发展现状。对旋转机械的常见故障及其机理做了介绍，从而明确了旋转机械故障诊断所需要的依据及诊断方法。整个系统进行了总体的设计，并对各个模块做了简要的介绍，比较了传统的故障诊断方法和小波分析方法，分析了在旋转机械故障诊断中引入小波分析的必要性。最后两章分别详细地介绍了系统中的两个核心模块的设计与实现。实践表明，该方法提高了故障诊断的准确性，取得了良好效果。同时，小波分析的结果还可以为以后的专家系统，智能诊断提供数据。-There15agreatdealofnon一stationarysingalsinmachineryoPeration.Buttraditional timedomainanalysisandrfequeneydomainanalysishvaemnaylimitationswith non一stationarysignals.Wavelettransofmrbasesonbaseufnction，leanrsthecharaeteristiesof trianglebaseofFourierTransofmrandwindowufnetionofShort一TimeFourierTransofmr， andofmrsoscillatoryanddamPedbaseufnction.It15Praisedasa“mathematiealmieroseoPe，， beeauseofitsmulti一sealeandtime一rfequeneycharaeteristiesandbeeomesanimPortanttool ofrdealingwithnon一stationarysials.

一个简单FM接收机的VHDL源码，很有参考意义-A simple FM receiver VHDL source code is very useful

音频波形显示和滤波,1、录音功能：CWaveIn类2、播放功能:CWaveOut类3、波形显示和滤波：CFilter类4、语音数据压缩解压：CG729aCompress、CGsmCompress 因为继承至同一个父类，所以它们的接口是一样的- Audio frequency profile demonstration and filter,1, recording function: CWaveIn kind 2, broadcast function: CWaveOut kind 3, profile demonstration and filter: CFilter kind 4, pronunciation data compression decompression: CG729aCompress, CGsmCompress because inherit to the identical father class, therefore their connection is same
