说明：  噪声中非平稳信号的频谱分析，基于MATLAB，实验报告一份(Nonstationary noise frequency spectrum analysis, based on MATLAB, a lab report)

This file contains a lab which is developed to implement a low pass filter using windowing technique. We study the way how to design FIR digital filters and how Matlab offers tools for the design.

MATLAB（矩阵实验室）是MATrix LABoratory的缩写，是一款由美国The MathWorks公司出品的商业数学软件。MATLAB是一种用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境。除了矩阵运算、绘制函数/数据图像等常用功能外，MATLAB还可以用来创建用户界面及与调用其它语言（包括C，C++和FORTRAN）编写的程序。(MATLAB (MATrix LABoratory) is The abbreviation of MATrix LABoratory, is a by The United States The MathWorks company production of a commercial mathematical software. MATLAB is a kind of for algorithm development, data visualization, data analysis and numerical calculation of senior technical computing language and interactive environment. Besides drawing function/data image matrix operations, commonly used functions, such as MATLAB can also be used to create the user interface and the calls to other languages (including C, C++ and FORTRAN) program. )
