摘要
采用Java语言实现了离散时间系统频率响应特性的动态演示,以JavaApplet的形式嵌入网页中运行。利用鼠标响应事件形象地刻画了零极点的位置对频率响应特性的影响,并提出了界面设计层次图的思想。其动态性、交互性、界面设计等方面都具有独到之处,丰富了教学形式,对信号与系统课程的网上教学做了有益的尝试。
By means of embedding Java Applet in Web page, dynamic displaying frequency response of discrete-time system is realized. Responding mouse events are used in order to vividly depict the influence of the positions of zeros and poles on frequency response characteristic and the idea of layer map in interface design is put forward. The program has shown originality in the dynamic property, interactive property and interface design, etc. This is also a beneficial trail in how to teach Signal & System on the Web.
