摘要
"数字信号处理"和"信号与系统"等信号类课程对数学要求较高,复杂繁冗的数学推导和证明容易导致学生产生畏难情绪,影响教学效果。本文以周期序列的离散傅立叶级数和傅立叶变换的推导为例,就教师如何用简单的或学生所熟悉的数学知识,进行深入浅出的教学进行了探讨。
Teaching process of signal courses , such as Digital Signal Processing , Signals and Systems , requires better ground of mathematics. Complicated derivations and proofs often make students to feel difficult , and have unfavourable effect on studies . Taking discrete Fourier series and Fourier Transform of periodic sequence as an example, this paper expounds how to simplify those abstruse theory by using straightforward mathematical knowledge which students are well-informed.
