摘要
周期信号的分解与合成是"信号与系统"课程中一个重要的教学内容,其理论基础是傅里叶级数,对高职院校的学生而言理解有一定难度.为了使学生易懂易学,以典型的周期矩形信号为例,首先在理论讲解时引入了信号分解与合成的MATLAB仿真图形,使学生对信号的分解和合成过程有视觉上的直观认知,有助于理论知识的消化;然后采用RZ8664型信号与系统实验箱对矩形信号的分解与合成进行理论验证,并与MATLAB的仿真结果进行实验对比分析,所得的实验结果能使学生更好地理解和掌握信号分解与合成的原理,在实际教学中取得较好的效果.
Periodic signal＇s decomposition and composition is an important teaching content in the Signal and System Course, and its theoretical principle is the Fourier series,however,for those students in vocational colleges, it is difficult to understand this complex mathematical description. To help students understand and learn more easily, taking typical rectangular signal as an example, the simulation figures of signal＇s decomposition and composition based on MATLAB are first introduced in theoretical teaching, which facilitates students＇ visual perception of the process of signal＇s decomposition and composition and helps them digest the theoretical knowledge. Furthermore, the theoretical proof of the rectangular signal＇s decomposition and composition is done by using the RZ8664 test box and the experimental results of RZ8664 test box are compared with the simulation results of MATLAB. The experimental conclusions obtained help students understand better the principle of the signal＇s decomposition and composition, and better teaching efficiency is obtained in fact.
