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)

用相位相关方法做的图象拼接程序,可进行图象拼接(Phase correlation method used to do image stitching process, images can be spliced)

说明：  这是一个完整的遗传算法子程序1,里面包含了各个子程序,运行没问题.(This is a complete genetic algorithm subroutine 1, which contains various subroutines to run no problem.)

灰色预测是就灰色系统所做的预测。所谓灰色系统是介于白色系统和黑箱系统之间的过渡系统。其具体的含义是:如果某一系统的全部信息已知为白色系统，全部信息未知为黑箱系统，部分信息已知，部分信息未知，那么这一系统就是灰色系统。(Grey prediction is the prediction of grey system. The so-called grey system is a transitional system between the white system and the black box system. Its concrete meaning is: if all information of a system is known as a white system, all information is unknown as a black box system, some information is known, and some information is unknown, then this system is a grey system.)

Different beamforming methods

该代码由matlab编写而成，主要用于查值计算(The code from matlab prepared, mainly for search terms)

ep. // Modules communicating with external circuits should normally be disabled // before entering a sleep mode that will stop the module operation. // Make sure the USART dumps the last message completely before turning it off. while(!usart_tx_empty(EXAMPLE_USART)) pcl_disable_module(EXAMPLE_USART_CLOCK_MASK)

说明：  一份详细的matlab手册，里面有关于matlab各个函数的详细介绍及例子(Matlab a detailed manual, which all function on matlab detailed introduction and examples)
