《信号与系统》的教学目的是让学生掌握信号与系统分析的基本理论和基本方法。为了让学生更好地掌握知识点,需要一定量的习题加以训练。由于傅里叶变换及基本性质一直是教学中的重点和难点。本文以求解信号的傅里叶变换为例,提出利用一题多解法来拓宽学生的解题思路,提高学生的学习兴趣,培养学生的工程思维能力。
The purpose of the teaching of Signal and System is to equip students with the basic theories and basic methods of signal and system analysis. In order for students to better grasp the knowledge point, you need a certain amount of exercises to be trained. Due to the Fourier transform and the basic nature of teaching has always been the focus and difficulty. In this paper, taking the Fourier transform of solving signal as an example, this paper proposes to use one-item multi-solution to broaden students ’thinking of solving problems, to improve students’ interest in learning and to develop their engineering thinking ability.
