代码说明:

数字信号处理,各种滤波器。数字滤波器的实用型式很多,大略可分为有限冲激响应型和无限冲激响应型两类,可用硬件和软件两种方式实现。在硬件实现方式中,它由加法器、乘法器等单元所组成,这与电阻器、电感器和电容器所构成的模拟滤波器完全不同。数字信号处理系统很容易用数字集成电路制成,显示出体积小、稳定性高、可程控等优点。数字滤波器也可以用软件实现。软件实现方法是借助于通用数字计算机按滤波器的设计算法编出程序进行数字滤波计算。

    Matlab的数理统计工具箱是Matlab工具箱中较为简单的一个,其牵扯的数学知识是大家都很熟悉的数理统计,因此在本文中,我们将不再对数理统计的知识进行重复,仅仅列出数理统计工具箱的一些函数,这些函数的意义都很明确,使用也很简单,为了进一步简明,本文也仅仅给出了函数的名称,没有列出函数的参数以及使用方法,大家只需简单的在Matlab工作空间中输入“help 函数名”,便可以得到这些函数详细的使用方法。(Mathematical Statistics Toolbox Matlab Matlab toolbox is a relatively simple one, it involves mathematical knowledge is the number of people are familiar with statistics, so in this article, we will no longer be on the knowledge of mathematical statistics to repeat, only lists Mathematical Statistics Toolbox functions that the meaning of these functions are very clear, very simple to use, in order to further condensed, this article only gives the name of the function, the parameters of the function is not listed, and the use of methods, we simply Enter the workspace in the Matlab " help function name" , it can be to use these functions in detail.)
