create a gaussian bell

DSP using matlab is one of the good book for developers and engineers.

在现代测试技术中，考虑到传感器特性，针对传感器特性曲线非线性问题的补偿(In modern testing technology, taking into account characteristics of the sensor, the sensor characteristic curve for the compensation of nonlinear problems)

QFSK加高斯噪声后，在0-10dB信噪比下，误码率曲线绘制(After QFSK plus Gaussian noise at 0-10dB SNR, BER curves plotted)

这里面的是matlab代码，能够实现图像的分割和特征的提取，很实用(There is a matlab code to achieve segmentation and feature extraction of image，Very practical)

说明：  用Matlab实现中值滤波，均值滤波以及高斯滤波(Using Matlab to achieve median filter, mean filter and Gaussian filter)

说明：   Buck－Boost电路的建模与仿真主程序

综合实验，基于matlab语言。希望对大家有用(Comprehensive experimental matlab. )

数字信号定时子程序，用于定时信号的最佳采样点。(Digital signal timing subroutine for the optimal sampling point timing signal.)
