信号与系统仿真平台的设计

Design of signals and systems simulation platform

针对当前信号与系统课程教学中存在的问题,在面向对象设计思想的指导下,利用层次化的设计方法,借助MATLAB的信号处理工具和GUI图形用户界面功能设计并开发了一个信号与系统的仿真平台分析软件。在该仿真平台上用户可以选择连续或者离散部分,在每一部分可以对其相应的信号及系统进行时域、频域以及复频域的变换,用户可以非常直观的了解他们之间的运算关系。平台界面友好,使用简单,充分体现了该仿真平台的综合性、直观性、应用灵活性。

Aiming at the current problems in teaching of signals and systems, under the guidance of the object-oriented design method, A set of analysis software for signals and systems simulation platform is designed by using signal processing tool and graphical user interface in MATLAB, through the hierarchical design method.Users can choose continuous portion or discrete portion at this platform. Signals and systems have been analyzed in time domain and transform domain for each part. Users can comprehend the arithmetic relationship between them easily. The platform has the advantage of friendly interface and is easy to use. It was approved that the simulation platform is integrated, intuitive and flexible.
