ve-DYNA® 为用户提供了车辆动力学、车辆非线性行为的可配置仿真模型。用户根据自己的工程问题选择合适的车型（轿车，货车，拖车）和适当的版本（低级，标准，高级）就能实现不同的应用。用户基于模型就能开发自己的控制算法或者部件，然后通过离线仿真和硬件在回路仿真来进行检验和验证。只需要进行鼠标键盘的操作，就可以对种种的动力学问题进行分析，比如悬架动力学，车辆动力性或操纵稳定性。这样 就 能够减少昂贵而且费时甚至是危险的实车试验。可以在无人监控的情况下完成整个的测试、优化和系统验证 。本文为veDYNA软件的相关例程介绍。(ve-DYNA ® provides users with vehicle dynamics, nonlinear behavior can be configured vehicle simulation model. Users according to their engineering problems select the appropriate models (cars, trucks, trailers) and the appropriate version (low, standard, advanced) will be able to implement different applications. Users can develop their own model-based control algorithms, or parts, and then off-line simulation and hardware in the loop simulation to be tested and verified. Only for mouse and keyboard operation, it can analyze the various dynamics, such as suspension dynamics, vehicle dynamic performance or handling and stability. This can reduce the costly and time-consuming and even dangerous in real vehicle tests. No one can monitor the situation in the completion of the testing, optimization and system verification. This article related to software routines for the veDYNA introduction.)

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)
