一本介绍在matlab下经典外国书籍，英文版本。(Matlab an introduction at the next classic of foreign books, the English version.)

IIR数字滤波器的模拟，与一些计算过程的计算机化，是标准课本的一个计算过程的程序化(IIR digital filter simulation, and the computerization of some computational process, is the standard textbook procedure for the calculation of a)

说明：  用Matlab实现高速数据采集自动化 数据采集卡的MATLAB编程(Matlab high-speed data acquisition with automated data acquisition card MATLAB programming)

通信原理课程做的大作业，关于正交调制的。(communication theory courses do the work, on the orthogonal modulation.)

实现语音信号通过低通滤波器后，得到频谱，并且输出滤波前后的图形。(Voice signal through a low pass filter to obtain a frequency spectrum, and outputs the graphic before and after filtering.)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)
