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.)

TestExceptionExt
Mingw下追踪崩溃信息的代码,整合了CodeProject上老外的代码和云风的Mingw的Backtrace代码,在32位和64位下编译运行通过,执行成功,使用Qt-Qmake生成的Makefile,32位和64位的问题主要是在于线程环境寄存器名字改了.效果怎么说呢,有帮助,但是不是每次都中.呵呵!有兴趣的看看.(the code for getting Some trace information runtime.)

DemoTest
将射频卡放在天线有效范围内，指定读/写地址，点击<读卡>，系统对该卡进行连续的读/写操作，直至用户点取<断开连接>按钮为止。同时将每个操作步骤调用的函数、操作结果及读出/写入的数据显示在列表框中。(The radio frequency card is placed in the effective range of the antenna, the read / write address is specified, the read card is clicked, and the system can read / write the card continuously until the user points out the disconnect connection. At the same time, the function, operation result and read / write data of each operation step are displayed in the list box.)

sift
说明： SIFT，即尺度不变特征变换（Scale-invariant feature transform，SIFT），是用于图像处理领域的一种描述。这种描述具有尺度不变性，可在图像中检测出关键点，是一种局部特征描述子。 该方法于 1999 年由 David Lowe 首先发表于计算机视觉国际会议（International Conference on Computer Vision，ICCV），2004 年再次经 David Lowe 整理完善后发表于 International journal of computer vision（IJCV） 。截止 2014 年 8 月，该论文单篇被引次数达 25000 余次。(来自百度)(SIFT, namely Scale-invariant feature transform (SIFT), is a description used in the field of image processing. This description has scale invariance and can detect key points in images. It is a local feature descriptor. This method was first published by David Lowe at the International Conference on Computer Vision (ICCV) in 1999 and published in the International Journal of Computer Vision (IJCV) in 2004 after it was sorted out and perfected by David Lowe again. As of August 2014, more than 25,000 citations have been cited. (From Baidu))
