| 摘 要： | 分析了《信号与系统》教学中三个重要的知识点。一是偶函数在一个周期内积分不一定为零的观点；二是FS和FT之间的关系，FT是周期趋于无穷大时FS的特例；三是序列移位的规律，它不仅与移位常数前的符号有关，而且和序列变量前的符号有关。并通过例题充分说明了这三个观点。

| Abstract: | Through some samples, this article analyzes three important knowledge points in teaching the course Signal and System. One is that the integral of even function in a cycle is not necessarily zero, another is about the relationship between FS and FT, and FT is the special case of the FS while the cycle tends to be infinity. And the third point explains the laws of sequence shifting, which is related with the mark not only in front of shifting constant but also in front of sequence variable. |

| Keywords: | Signal and System integral of periodic function relationship between FS and FT shifting of sequence |
