本文分析了语音数字信号的采集来源以及其预处理。通过实例,利用Matlab对语音信号进行时频变换与分析,同时构造一个固定频率的干扰信号,对两个信号进行合成,设计数字滤波器,实现对语音信号的F IR、IIR滤波处理,最后在时域和频域中对信号进行分析比较。(This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.)

2DWaveletsimpression
由于小波及小波包技术可以将信号或图像分层次按小波基展开,所以可以根据图像信号的性质以及事先给定的图像处理要求确定到底要展开到哪一级为止,从而不仅能有效地控制计算量,满足实时处理的需要,而且可以方便地实现通常由子频带、层次编码技术实现的累进传输编码(即采取逐步浮现的方式传送多媒体图像)。这样一种工作方式在多媒体数据浏览、医学图片远程诊断时是非常必要的。另外,利用小波变换具有放大、缩小和平移的数学显微镜的功能,可以方便地产生各种分辨率的图像,从而适应于不同分辨率的图像I/O设备和不同传输速率的通信系统。相比之下,利用KL变换进行压缩编码,只能对整幅图像进行;而利用小波变换则能够比较精确地进行图像拼接,因此对较大的图像可以进行分块处理,然后再进行拼接。显然,这种处理方式为图像的并行处理提供了理论依据。
(As the little affected wavelet packet technology can signal or image stratified by wavelet and so on according to the nature of the image signal and the image processing requirements given in advance exactly sure on to what level, and so far not only can effectively control of calculation and meet the needs of the real-time process, and can be easily realized by sub-band usually coding technology, levels of the realization of the progressive transmission (that is, take gradually emerged coding the way multimedia image transfer). Such a way of working in multimedia data browse, medical image remote diagnosis is very necessary. In addition, by using wavelet transform has amplification, narrowing the mathematics of peace move microscope function can be easily produce all sorts of resolution image in order to adapt to different resolution in )
