saber 对于三相逆变电路的仿真原理图，可实现任意频率可调的逆变驱动电路(saber for the simulation of three-phase inverter circuit schematic can be realized at any frequency inverter drive circuit adjustable)

给出一段噪声音乐信号，用滑动平均滤波器进行处理，观察改变滑动窗口宽度对声音效果的影响。 （1）读取一段噪声信号，画出未处理噪声信号的时域波形和信号频谱图； （2）在Matlab中利用滑动平均滤波器对噪声信号进行处理，得出处理后的图像； （3）改变滑动窗口的宽度，观察处理后噪声以及图像得出对效果的影响。(A piece of noise music signal is given. It is processed with a sliding average filter to observe the effect of changing the width of sliding window to the sound effect. (1) a noise signal is read and the time domain waveform and signal spectrum map of the unprocessed noise signal are drawn. (2) in Matlab, a sliding mean filter is used to process the noise signal, and the image after processing is obtained. (3) to change the width of the sliding window, to observe the noise after processing and to the effect of the image.)

内有两个MATLAB程序，主要用于语音增强：一个用于向纯净语音文件(wav)添加高斯白噪声，信噪比可选；另一个文件用于测量语音信噪比，对语音增强效果判断(MATLAB, there are two procedures, mainly used for speech enhancement: one for the pure audio files (wav) add white Gaussian noise, SNR optional another document used to measure the voice signal to noise ratio, the effect of speech enhancement judge)

电力电子技术 西安交通大学 王兆安 书配套MATLAB/simulink 仿真(Power Electronics Technology, Xi an Jiaotong University Wang Zhao book package MATLAB/simulink simulation)

在SENSE成像中如何将中间图像转化为最终图像，就要用到这个程序(Using specfied sampling vector to generate a 2D aliasing matrix. The sampling vector is a vector of n-entries of either 0 or 1, where 0 indicates no k-space line acquisition and 1 indicates k-space line is acquired in the accelerated scan. For example, a sampling vector of [0 1 0 1 0 1 0 1 0 1] indicate the 2-fold acceleration with 8 phase encoding lines. The aliasing matrix is calculated based on Fourier imaging)

用remez算法实现低通滤波器 并绘制频谱图(Remez algorithm using low-pass filter and draw a spectrum map)

This matlab script is for ploting a graph by accessing serial port data in real time. Change the com values and all variable values accroding to your requirements. Dont forget to add terminator in to your serial device program. This script can be modified to be used on any platform by changing the serialPort variable.

说明：  运用遗传算法的工具箱解决宽带雷达吸波结构的优化问题(use genetic algorithms to solve the toolbox broadband radar absorbing structure of the optimization problem)
