XIANG QIAN. Listen to the Fourier Series——A Study on the Teaching Reform of "Signals and Systems". [J]. 2012, 58(S2): 120-124. DOI: 10.14188/j.1671-8836.2012.s2.046.
"Signals and Systems" is an important basic course for electronic information professional.In order to arouse students’ interest of study and enhance the teaching quality of this course
this paper introduced Fourier series for periodic signals with the help of music as an example.We put forward the idea of using the concepts and analysis methods about signals and systems in real-world applications
which is a significant attempts for the innovation of the teaching methods.
