摘要
为提高电子技术中关于频率响应的教学质量,提出一种基于DSP Builder/Matlab的滤波器仿真实验平台设计方法。以IIR数字滤波器为例,利用DSP Builder模块搭建图形化IIR滤波器模型,利用Matlab程序化设计IIR数字滤波器,分别仿真验证滤波器功能、对比校验实验效果。该仿真实验平台将电子技术、数字信号处理、EDA技术联系起来,实现简单,效果生动、形象,有利于学生理解和掌握相关理论知识。
In order to solve the problems with abstract of frequency response of electronic technology teaching content,difficult to understand,insufficient of hardware resources,a kind of simulation experimental platforms based on DSP Builder/Matlab is proposed.Taking the infinite impulse response digital filter as an example,the working principle of infinite impulse response is introduced,and a graphical model of the IIR filter is built by using of DSP Builder module.In addition,the design of IIR filter is realized by use of Matlab programming,the simulation result of which is contrasted with the one of DSP Builder module,and the function of filter is verified.Electronic technology,digital signal processing and EDA technology are integrated by this simulation experimental platform.It is easy to realize and the simulating effect is vivid.With the help of simulation experiment,the students＇ understanding theory knowledge and analytical skills will be improved largely.
