卷积动态仿真的设计与实现

为了生动地演示卷积的动态效果，搭建一个整体架构来实现卷积的仿真，用Java类对架构的关键模块作了详细的说明，封装了信号处理类和表达式分析类，设计了坐标系中动态调整图形显示的算法，利用多线程和双缓冲技术实现了卷积的动画效果。测试结果表明，仿真具有很好的交互性和动态性，形象地展示了信号卷积的动态过程和基本性质。并且设计方案具有较大的通用性，把其中涉及到卷积计算的特定内容稍做修改，也可以进行信号与系统课程中其它相关知识点的仿真。

Design and Implementation of Convolution Dynamic Simulation

A general framework is constructed for simulating signal convolution vididly and some key modules are interpreted by several Java classes. The classes of signal processing and expression analysis are encapsulated. The algorithm of dynamic adjustable graphic show in coordinate system is designed and the dynamic convolution purpose is realized by muhithread and dual buffer technologies. The simulation result not only indicates good alternating and dynamic characteristics,but also presents a concrete process and fundamental properties of convolution. Moreover,this design scheme has large universality ,which can do simulation of other related knowledge points in signal and system, once making a little change to the special content concerning with the convolution.
