摘　　要：离散卷积和在分析线性时不变离散滤波系统中起着很重要的作用,初学者难以很好地掌握和应用。提出一个系统利用MATLAB的图形用户界面,设计其计算平台。该系统平台可自设长度、速度、改变参数,把抽象的理论知识转变成直观易懂的动态演示,加深学习者对序列卷积运算的理解和掌握,进而实现离散系统的零状态响应的计算。The discrete convolution plays a very important role in the analysis of the LTI system, but it is difficult to master well to beginners. Designs a convolution computation platform by MATLAB GUI, the length, speed and parameters can be set by the system, changes the ab- stract theory into a straightforward dynamic demonstration. It can help the learners to understand and grasp the discrete convolution, and to realize the discrete calculation of the zero state response.
