基于DSP的信号与系统仿真实验平台的设计

提出了一种基于DSP的信号与系统仿真实验平台实现方案．这一实验平台采用了将软件和硬件有机结合来进行仿真的方法，当用户在计算机界面上进行实验操作时，实验结果波形可以在实际的示波器上显示出来．仿真实验平台的软件方面主要是编写了一个在主机上运行的用户界面，用以将仿真实验的内容完整地展示给用户，并允许用户进行实验操作．硬件方面则使用一块以DSP系统为核心的实验板与主机通信，主要功能是将用户进行的实验操作进行计算，并将结果通过仿真，在示波器上显示出来．从而使使用者获得较为真实的实验感受，对信号处理有一个更深层次的认识．

A DSP-based experimental platform of signal and system

An experiment equipment for signal and system based on DSP, which combined both the software and the hardware, was developed. The results of experiment could be shown on the oscillograph when users operate on the host PC. An interface on hose PC was also developed, exhibiting all the experiment contents. Users can do their experiments on the platform. A DSP system was used to communicate with host to compute the experimental data input by users and to show the result on an oscillograph. The users will feel like a real experimental environment and get a further understanding of the signal processing.
