对心电信号的QRS波进行前期处理，主要是下载信号和对信号去噪滤波。(Of the QRS wave of ECG to pre-treatment, mainly to download signals and to signal de-noising filter.)

说明：  1、以不同的视角观察球面 和圆柱面 所围区域。2、画出s(t)=cos(2/3πf0t)的曲线及其付氏变换的曲线.设:f0=1KHz,时域分辨率 dt=0.01ms, 采样点数 N=2k, k>10.（均为M文件）(One to observe the different angles of spherical and cylindrical surface region by Wai. 2, draw s (t) = cos (2/3πf0t) curve and its Fourier transform curve. Established: f0 = 1KHz, time-domain resolution of dt = 0.01ms, sampling points N = 2k, k)

it s very useful to optimize filter and synthesize antenna arrays with low side lobe

FIR filters in Matlab

本matlab源代码提供了，互动峰值检波器函数。互动峰值检波器是在波动信号中检出最大幅值的装置。(Matlab source code provides the interactive peak detector function. Interactive peak detector signal is detected in the maximum amplitude wave devices.)

JUST FOR FUN....THIS MODEL JUST EXPOSES MY FAVORITE CUNT S PROGRAMMING SKILLS...SHE REALLY IS A BBOB WHEN IT COMES TO PROGRAMMING

APF有源滤波器仿真，两电平，三相四线制，电力电子技术，matlab simulink(APF active filter simulation, two-level, three-phase four-wire system, power electronics technology, matlab simulink)

DCT给灰度图像加二值的水印信息，运行显示四幅图，分别是原图像，水印图像，加水印的图像和提取的水印图像(DCT to gray image plus two watermark values, run the show four maps are the original image, watermark image, add watermark image and extracted watermark image)

说明：  IEEE33节点的潮流计算，比较适合学习(Power flow calculation of 33 nodes)
