实现了方波、正弦波、三角波的输出，同时在LCD模块中用状态机的方法实现LCD的对应显示：当输出正弦波，LCD显示“SIN”；当输出方波，LCD显示“REC”；当...

子波变换与子波分析-wavelet transform and wavelet analysis

小波十讲，极经典的小波教程，完全中文，是学习小波理论的权威及入门的良好教程。读者一定会从中获益匪浅。-Ten Lectures on Wavelet, Wavelet Tutorial very classic, completely in Chinese, is to learn from the authority of wavelet theory and the entry of good tutorials. Readers will certainly benefit from them.

小波变换源代码，实现了几种不同的小波变换-Wavelet Transform source code, to achieve a number of different wavelet transform

由于小波变换具有良好的时频分析特性，已经广泛应用于各种信号分析领域。由于小波变换算法的复杂性，如果直接计算小波变换，所需内存较大，耗时较长。尽管当今处理器芯片运算速度得到了大幅度的提高，但仍然在实时性上不能满足要求。为了简化计算过程，人们相继设计了一系列的快速算法来计算小波变换，以降低其运算次数。-Since the wavelet transform has good time-frequency analysis features, has been widely used in various fields of signal analysis. Wavelet transform algorithm as a result of the complexity, if the direct calculation of wavelet transform, the larger memory requirements, a longer time-consuming. Despite the computational speed of today

监控程序，实现数据采集，数据虑波，同时显示-monitoring procedures, data collection, data taking into account waves, also showed

这是一组二维小波变换的经典程序，对研究小波的很有用，里边有对应说明-This is a group of two-dimensional wavelet transform of the classical procedures, the study of wavelets useful, inside there is the corresponding description

提升方法实现小波变换，大大提高了小波变换的速度，并且不会降低图像恢复质量，很有价值的算法实现-upgrade method wavelet transform and greatly enhance the speed of wavelet transform, and will not reduce the image restoration quality, great value Algorithm

Apart from the Haar transform, there is no orthogonal wavelet transform

静态切分窗口的曲线y=ax*x+10*x+10图，根据a在[-10，10]区间变化时，曲线随着变化-static window splitting the curve y = ax 10* x* x 10 maps, in accordance with a [-10, 10] interval changes, in keeping with the changing curve
