一天征服傅里叶变换，对傅里叶变换做了浅显易懂的分析，对学习数字信号处理有帮助。(One day conquer the Fourier transform, made accessible for the Fourier transform analysis, is helpful to study digital signal processing.)

MATLAB实用程序100例子仿真,同学们可以先看看，希望有所帮助( MATLAB emluator100 of example)

采用HRTF数据合成频域补偿曲线，实现双声道虚拟环绕声(SRS-3D)(the dual-channel virtual surround sound system using HRTF date (SRS-3D))

说明：  本模型是基于matlab Simulink搭建的PQ控制和下垂控制模型，可以用于微电网的并网和孤岛运行PID参数已经调好，效果理想，可以供参考。(This model is based on the model of PQ control and droop control built by MATLAB Simulink. It can be used in the parallel operation of microgrid and islanding operation. The PID parameters have been adjusted, and the effect is ideal, which can be used for reference.)

contrnuous stir tank reactor model

说明：  32qam调制在AWGN信道中的符号误码率(32qam modulation symbols in the AWGN channel BER)

该功能能实现Matlab截断效应的仿真，绘图。直白的看出截断效应的效果。(This feature is able to achieve Matlab simulation of the truncation effect, drawing. Straightforward to see the effect of the truncation effect.)
