1.题目：数字滤波器的设计与应用 2.设计要求：利用 Matlab 软件,以复合信号分离为例,对 “数字信号处理” 课程中 的谱分析 、数字滤波器设计和信号滤波这三个过程进行了仿真实现,给出了仿真结果。 3.具体步骤： （1）构造原始信号s(t) （2）画出s(t)的频谱 （3）设计ellipse数字滤波器(IIR)，包括低通，带通，带通，并显示幅频特性 （4）用得到的滤波器进行滤波，分离出三路信号，观察时域波形和幅频特性 （5）用三路信号s1,s2,s3尝试重新合成原始信号 4.问题：为什么重新合成的信号和原信号不相等呢？谁能解释一下？谢谢,QQ:664519036( 1. Title: Digital Filter Design and Application 2. Design requirements: use of Matlab software to composite signal separation, for example, on "Digital Signal Processing" course Of the spectral analysis, digital filter design and signal filtering process carried out three Simulation, the simulation results. 3. Concrete steps: (1) construct the original signal s (t) (2) Draw s (t) of the spectrum (3) design ellipse digital filter (IIR), including low pass, band pass, band pass, and shows amplitude-frequency characteristics (4) filtering with a filter obtained by the isolation of three signals, observed time-domain waveform and frequency characteristics (5) with a three-way signal s1, s2, s3 try to re-synthesis of the original signal 4. Question: Why is re-synthesized signal and the original signal is not equal to it? Who can explain? Thank you, QQ: 664519036)

说明：  metropolis-Hastings samplermetropolis-Hastings抽样的matlab实现(metropolis-Hastings samplermetropolis-Hastings in matlab)

采用PCA提取人脸特征,先计算M个图像的平均值脸，再求出各特征值脸。(Using PCA for face feature extraction, first calculate the average face image of M, and then find the face value of each characteristic.)

这是一个有关parzen窗估计的代码，用来估计概率密度函数。采用了方窗、指数窗、高斯窗函数三种核函数，附有matlab程序。(This is an estimate of the code related to parzen window, used to estimate the probability density function. With a side window, the index window, Gaussian window function three kinds of kernel function, with matlab program.)

CA交通流模型，嗯，就是这个了。。。不错，应该行吧(CA model)

说明：  三个复正弦信号的信噪比分别为SNR1 =30dB， SNR2 =30dB和SNR3 = 27dB。假设信号样本数为1000，FIR 滤波器的抽头个数为4。基于奇异值分解的MVDR 方法进行信号频率估计的仿真实验，获得功率谱密度函数的估计。(A power spectrum estimation algorithm named mvdr is introduced in this program)

补充orchard Release版本没有的Rule模块（已编译）(orchard rule modal)

说明：  用于海洋密度计算和绘图 的程序包 可以直接调用相关函数(Density calculation for the ocean and drawing packages can be directly related to the function call)
