sigma-delta ADC的信噪比等的计算(the calculation of SNR、SNDR and so on of sigma-delta ADC)

说明：  在数字信号处理，采用滑动平均的方法消除噪声(In digital signal processing, using moving average method to eliminate noise)

说明：  自己写的isodata聚类程序，已经在matlab下调试验证通过。(Wrote it myself ISODATA clustering procedure has been adopted to verify matlab debugging.)

图像增强实验:图像一致性增强滤波器,基于一种各向异性的扩散过程，它首先能够去除图像的噪声，然后在此基础上增强图像纹理的一致性。matlab实现含报告 (image enhance)

Most practical filters exhibit steady roll-off characteristic, in contrast to the sharp transition from the pass and stop bands. The important families of filters are: Butterworth, Chebyshev and Elliptic. As part of this lab, we study and design Butterworth filters. Butterworth filters are simple to design and have a maximally flat pass band response. In contrast the Chebyshev and Elliptic filters are difficult to design and have ripples in pass/stop band but have sharper roll off characteristics than Butterworth filters.

MATLAB是一门计算机编程语言,取名来源于Matrix Laboratory,本意是专门以矩阵的方式来处理计算机数据,它把数值计算和可视化环境集成到一起,非常直观,而且提供了大量的函数,使其越来越受到人们的喜爱,工具箱越来越多,应用范围也越来越广泛 (MATLAB is a computer programming language, name comes from Matrix Laboratory, is meant to the Matrix of the special way to deal with the computer data, it put the numerical calculation and visual environment integration to together, very intuitive, but also provides a lot of function, make it more and more popular, more and more toolbox, application more and more widely )

说明：  本代码用matlab编程，计算了duffing振子（杜芬振子）和非线性加幂律振子的响应，使用的方法是Newmark β方法和Runge-kutta方法，资源内容包括matlab代码和演示PPT，仅供学习使用，有问题可以留言。(This code uses MATLAB programming to calculate the response of Duffing oscillator and nonlinear plus power-law oscillator.)
