lowpass_FIR

通信原理中功率谱密度的仿真，仿真了不同占空比，等概、非等概双极性矩形随机信号的归一化功率谱密度，并分析不同信号（不同占空比，等概非等概）所包含的频谱分量，有无直流分量和定时分量信息(Communication theory in the power spectral density of the simulation, the simulation of different duty cycles, such as almost, almost bipolar rectangular Non-random signal normalized power spectral density, and the analysis of different signals (different duty cycle, etc. None of the other Summary) contains the spectrum component, with or without DC component and time component information)

可用于图像处理，提取图像中隐藏信息，并对图像进行修改(Can be used for image processing, extracting images hidden information, and modify images)

数字调制FSK仿真的完整程序，很有用的哦(Digital modulation FSK simulation complete program, very useful oh )

炉温模糊控制的matlab simulink仿真（文档加程序）(Furnace temperature fuzzy control simulation matlab simulink (document plus program))

说明：  利用FFT分析方波信号的频谱，讨论采样点数、采样频率对谱分辨率的影响。对数据叠加白噪声后再次分析实验结果。(Square-wave signal using FFT spectrum analysis to discuss the sampling points, the sampling frequency of the impact of spectral resolution. White noise superimposed on the data after analysis of experimental results.)

System will automatically delete the directory of debug and release, so please do not put files on these two directory.
