RZ8664型实验箱在信号时域分析实验教学中的应用

The Application of RZ8664 Test Box in the Experimental Teaching of Signal Time-domain Analysis

信号时域分析方法是"信号与系统"课程中的重点教学内容,涉及到常见信号的数学描述、波形分析、综合变换、卷积分析、全响应等知识,数学公式较多,理论性较强,学生不易理解和应用.为了使学生易懂易学,在实践教学中采用RZ8664型信号与系统实验箱,连接相应的信号处理模块后,通过示波器可以直观地观测到信号时域分析的实时结果,增强学生对理论知识点的理解,在一定程度上提高学生的动手能力和独立分析问题能力,取得较好的教学效果.

Methods of signal time-domain analysis are the important teaching contents in Signal and System Course,which involve some contents of common signals,such as mathematical description,wave analysis,synthesized transformation,convolution analysis,complete response and so on. It is difficult for students to understand and apply them because of too many mathematical formulas and complex theory. In order to hel p students understood and learn more easily,the RZ8664 test box is used in our practical teaching. When relative modules of signal processing are linked,the real-time results of signal time-domain analysis can be directly observed by scope,which can enhance students＇ comprehension of theoretical knowledge,and improve students＇ practical ability and analyzing ability independently,as well as obtain better teaching efficiency.
