采用差分阈值法对心电信号QRS波进行特征提取ecg0

数字滤波器在数字信号处理领域中已经得到广泛应用,MATLAB 软件的频谱分析和滤波器的分析设 计功能很强,从而使数字信号处理变得十分简单。利用MATLAB 的数字滤波器设计工具箱可以快速有效地设计各种数字滤波器,设计简单方便。介绍了IIR 数字滤波器的设计原理、步骤以及在MATLAB 中的实现。(Digital filter in the field of digital signal processing has been widely used, MATLAB software for spectrum analysis and filter analysis and design features strong, so that digital signal processing have become very easy. MATLAB using the Digital Filter Design Toolbox can quickly and efficiently design of digital filters, design is simple and convenient. Introduction of the IIR digital filter design principles, steps and in the implementation of MATLAB.)

说明：  基于MAT LAB 的 “信号与系统” 仿真实验，希望对大家有帮助(Based on MAT LAB' s &quot Signals and Systems&quot Simulation results, we want to help)

VC++调Matlab的简易程序，调出Matlab的figure图(VC++ tune simple Matlab program, bring up Matlab' s figure diagram)

此程序可用来对二维光子晶体带隙结构进行模拟绘图(This procedure can be used to two-dimensional photonic band gap structure to simulate the drawing)

说明：  时变参数向量自回归模型的估计代码以及模型应用方法(Estimation code and application of Time-Varying parameter vector autoregressive model)

这是一个在利用密钥产生随机序列，他能实现在伪随机序列的产生(This is a key generated using random sequence, he can achieve the pseudo-random sequence generation)

自适应程序matlab代码，有详细说明，很不错，适合初学者！(Adaptive procedure matlab code, a detailed description, it is good for beginners!)

美国学者无与非的总要资料很基础想学turbo码的人必需看good turbo code (good turbo code )
