摘　　要：为了使学生对数字信号处理课程中的数字滤波器部分有更深刻的理解和掌握,设计了一种基于MATLAB图形用户界面(GUI)的数字滤波仿真平台。该平台包括三大部分,具备注册、登录和修改密码功能的用户登录系统,程序法设计IIR和FIR数字滤波器,利用FDATool和Simulink来设计数字滤波器并滤波仿真。该仿真平台,可以对输入信号频率、采样频率和滤波器技术指标等参数进行实时调整修改,操作直观简便,框架清晰,设计合理,内容丰富,结果正确。该平台可应用于数字滤波器设计的工程实践,也可用于课程教学,有助于学生更好地理解滤波器相关知识,从而取得更好的教学效果。In order to enable students to have a deeper understanding and mastery of the course of the digital signal processing, one digital filtering simulation platform based on MATLAB GUI is designed. The platform consists of three parts, a user login system with registration, login and password modification, a programming approach to designing IIR and FIR Digital filter, and the use of FDATool and Simulink to design digital filter and realize filtering simulation. The simulation platform can adjust the parameters such as input signal frequency, sampling frequency and filter technical specifications in real time, along with other advantages such as simple operation, clear structure, reasonable design, complete content and correct result. This platform can be applied to the engineering practice, and also can be used in the course teaching, which is helpful for students to better understand the relevant knowledge of digital filters, further to achieve better teaching effect.
