| 摘 要： | MATLAB具有强大的图形编辑功能，能对信号处理中的很多问题用比较简单、直观、形象、易懂的方式表现出来。首先介绍MAT-LAB的句柄图形、图形对象、GUI控件对象以及对离散系统的零极点与频率特征的关系作了分析。然后详细地给出如何用MATLAB中的图形函数设计数字系统零极点与频率特征关系的动态实时显示动画界面。这个设计方式可以很容易应用于信号处理课程中其它很多难点问题。

| Abstract: | MATLAB has a powerful function of graphic compilation, which can represent many problem in signal processing with simple, visual and easy understandable methods. A brief introduction to the handle graphics, graphic object and GUI control object in MATLAB is given, the relation between pole-zeros and frequency characteristics of the discrete-time system is also analyzed. A program method using graphic function to design the animation interface, which displays dynamic real-time relation between pole-zeros distribution and frequency characteristics is presented in detail. This method can be easily used to represent other difficult problems in signal processing course. |
