【谷速软件】卷积的GUI 可以作为参考使用学习([Valley] GUI convolution speed software can use as a reference to learn)

这是数字信号处理的一本专业书，里面有许多的经典的例子，可以作为大家学习数字信号处理的教材。(This is a digital signal processing of a professional book, there are many classic examples, as we learn from digital signal processing of materials.)

说明：  录制一段个人的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用双线性变换法和窗函数法设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a personal voice signal, and recording the signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum for a given filter performance, the bilinear transformation and design of filter window functions and draw the frequency response filter then filter of their own design collection of the signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, analysis of signal changes playback audio signals Finally, a signal processing system interface design.)

采用matlab开发的SVM源码，包括四种核函数(about SVM)

基于matlab开发的通用有限元软件的源程序部分，最新版本(Matlab-based general-purpose finite element software development source part, the latest version)

Normalizes data between 0 and 1 (norm_RS1) or between -1 and +1 (norm_RS2)

说明：  OFDM系统是将一个用户的信息分别调制在了多个相互正交的子载波上面，对频率偏移非常敏感，OFDM同步技术非常关键，这里予以实现(OFDM system is a user' s information were prepared in a number of mutually orthogonal subcarriers above, is very sensitive to frequency offset, OFDM synchronization is critical to achieve here)

基于遗传算法的以最小二乘法为准则条件下的电动汽车与内燃汽车的成本对比(Cost comparison based on genetic algorithm, the least squares method for the guidelines under the conditions of electric vehicles with internal combustion automobile)

用来计算保角变换程序，可计算多角的保角变换(Used to calculate the conformal mapping procedures, Computable Polyhedrosis the conformal mapping)
