基于Matlab GUI的模拟带通滤波器的设计

Design of Analog Band-pass Filter Based on Matlab GUI

在传统的模拟带通滤波器设计过程中需要大量繁琐的数值计算,若手工计算则费时费力。在分析模拟带通滤波器设计理论和基于Matlab的图形用户界面(GUI)设计方法的基础上,利用Matlab GUI工具设计了具有通用性交互式切比雪夫模拟带通滤波器分析设计软件,并对软件中各控件回调函数的设计给出了详细的设计方法。用户只需要输入设计滤波器所需参数,然后选择相应的功能菜单,就可以得到滤波器的特性参数,并进行滤波器的性能分析。该设计解决了滤波器设计过程中大量繁琐的数值计算问题,为切比雪夫模拟带通滤波器的研究设计提供了有效的辅助工具。

Since the traditional design process of an analog band-pass filter needs a great deal of complex numeric calculations which use a lot of designer′s time and energy,a universal and interactive software,by which user can research and design the analog band-pass Chebyshev filter with simulation,is completed by using the Matlab GUI tool of filter design.The design method of active callback function in the software is given.The design is based on the analysis of analog band-pass filter design theory and the design method of graphical user interface（GUI） is based on Matlab.Users can obtain the characteristic parameters of the wanted filter by inputing some target parameters and choosing the corresponding function menu,and the performance,analysis for that filter can be conducted.Thus,a tool which can assist user to research and design an analog band-pass Chebyshev filter and avoid too much complex numeric calculation is furnished.
