摘要
针对数字信号处理课程公式繁多,内容晦涩难懂,文章设计了基于MATLAB GUI的数字信号处理课程可视化平台设计。平台设计的界面里包含着主界面和子界面,内容包括离散系统的时域和频域的分析,快速傅里叶(FFT)变换,有限长脉冲响应(FIR)和无限长脉冲响应(IIR)数字滤波器四大模块,涉及数字信号处理课程的主要内容。该系统有良好的交互性和可扩展性,实践证明,该平台的使用增强学习数字信号处理的效果。
in view of the numerous formulas and obscure content of digital signal processing,this paper designs a visualization platform of digital signal processing Based on MATLAB GUI.The interface of the platform includes the main interface and sub-interface.The content includes the analysis of discrete system in time and frequency domain,fast Fourier transform(FFT),finite impulse response(FIR)and infinite impulse response(IIR)digital filter,involving the main content of the course of digital signal processing.The system has good interactivity and expansibility.Practice has proved that the use of this platform promotes students’learning effect of digital sig⁃nal processing.
