摘　　要：以采样定理为教学实例,利用MATLAB实现《信号与系统》课程的实践教学.给出了临界采样、欠采样和过采样情况下采样信号及其重构或恢复原信号的过程.通过教学实践,学生充分理解和掌握《信号与系统》知识点,解决实际问题的能力得到提高.Introduce the teaching practice in course of signals and systems by MATLAB, taking sampling theorem as teaching instance. The procedure of sampling signal and original signal reconstruction is presented in the situations of critical sampling, undersampling and oversampling. The students can comprehend and master the knowledge of signals and systems, and their ability of solving practical question can be improved through teaching practice.
