摘要
数字信号处理作为电子通信专业的基础课程,涵盖了许多信号处理相关的内容,包括信号傅里叶变换、频谱分析以及数字滤波器设计等。其中,IIR滤波器和FIR滤波器作为经典的频域滤波器,是信号处理中最为基础的滤波器。通过对这两种滤波器的学习,将有助于后续复杂滤波器的设计。利用MATLAB的图形化接口,结合数字信号处理中滤波器设计的相关内容,开发了基于MATLAB的数字信号处理实验平台。该平台功能包括添加信号、叠加噪声以及IIR、FIR各滤波器类型的设计,不仅方便学生在课上直观地了解到频域滤波器的滤波过程,而且有利于在课后近一步学习与扩展滤波器设计。
Digital signal processing,as a basic course of electronic communication,covers a lot of signal processing related content,including signal Fourier transform,spectrum analysis,digital filter design,etc.Among them,IIR filter and FIR filter,as the classical frequency domain filter,are the most basic filter in signal processing.The study of these two kinds of filters will be helpful to the design of complex filters.In this paper,a digital signal processing experimental platform based on MATLAB is developed by using the graphical interface of MATLAB and the related content of filter design in digital signal processing.The platform functions include adding signal,overlay noise,IIR,FIR filter type design,not only convenient for students to intuitively understand the filtering process of frequency domain filter in class,more conducive to students to further study and expansion of filter design after class.
