摘要
利用数字示波器和自制的试验箱完成傅里叶级数的叠加和展开以及傅里叶变换的实验方案,帮助学生理解傅里叶分析的实质。把抽象理论通过实验体现出来,具有良好的教学效果。
Abstract： This paper put forward a kind experimental program using digital oscilloscope and a self- made test box which complete Fourier series expansion and superimposed and Fourier transform, help the students to understand the essence of Fourier analysis. The abstract theory was reflected through experiment, with good teaching effect.
