针对大学电类实验中频域相关内容偏少的现象,以滤波器设计为实验内容,将虚拟仪器技术中的波特图仪、FFT频谱仪等频域测量设备应用到"电子线路课程设计"的实验教学中.通过滤波器的设计、特别是滤波器特性的分析以及特性的实验验证等教学环节,强化学生对于频域相关知识的理解,同时依靠虚拟仪器技术也大幅度拓展"电子线路课程设计"课程在频域方面的实验教学空间.
Research on teaching method of filter design
Aiming at the phenomenon that there are few electrical experiments related to frequency do-main in college education,taking the filter design as the experimental content,it is proposed to apply Bode plotter and FFT spectrum analyzer used in virtual instrumentation technology to the experimental teaching of"electronic circuit course design".Through filter design,filter characteristic analysis and experimental verification in the course of experiment,students'understanding of frequency domain re-lated knowledge is strengthened.At the same time,based on the virtual instrument technology,it also greatly expands the experimental teaching space of"electronic circuit curriculum design"in frequency domain.
