摘要
针对"信号与系统"概念抽象,不易理解和掌握等问题,利用图形化编程语言LabVIEW构建"信号与系统"实验平台。介绍了该实验平台的系统构架和设计方法,给出了连续信号卷积、FFT、采样定理、FIR滤波器设计等4个实验设计示例。该平台能将抽象的概念变为形象、生动、直观的图形和实例,从而帮助学生更好地理解"信号与系统"的基本概念和理论,提高教学效果。
Aiming at the abstract concepts of signal and system,and the difficult to understand and grasp,a signal and system experiment platform based on LabVIEW is developed.The paper introduces the frame and design methodology of the experimental platform,and gives four experiments design examples,such as convolution,FFT,Sampling theorem,FIR filter by changing abstract concepts into vivid,visual graphics and examples,the platform can help students better understand basic concepts and theories of signal and system,and improve the teaching effect.
