摘　　要：《信号与系统》是信息技术类专业本科生的一门重要的专业基础课程。从取样定理这一重要理论出发,针对非带限信号的取样问题,以方波为例,利用MATLAB展示方波信号的取样过程,将抽象的理论进行可视化图形演示,从而加深学生对取样定理的理解和掌握,激发学生的学习兴趣,收到良好的教学效果。Signals and Systems is an important professional basic course for undergraduates majoring in information technology. Starts from the important theory of sampling theorem, for the sampling problem of non-band limited signals, and takes the square wave as an example, the sampling process of square wave is demonstrated by MATLAB. The abstract theory is showed by visualization. It has deepened the students＇ understanding and mastery of the sampling theorem and has excited the students＇ study interest and has received the good teaching effect.

关 键 词：信号与系统 MATLAB 取样 连续信号
