《信号与系统》课程是通信电子类专业重要的基础课程,在图像处理、信息工程、控制等领域具有重要地位。实际教学中,由于该课程需要一定的数学基础及理论性强,学生普遍感觉难以理解与掌握。为此,提出对《信号与系统》课程进行可视化教学,弱化理论推导、抽象概念动画化、学用结合。实现重点内容动态化、精炼化。可视化教学即完成教学任务、提高教学质量,又激发学生学习的兴趣和应用能力的培养。 The signal and system course is an important basic course in communication and electronics specialty and plays an important role in the field of image processing, information engineering and control. In the actual teaching, because the course needs certain mathematics foundation and the theory is strong, the student generally feels difficult to understand and master. To this end, the author proposes to visualize the teaching of “Signal and System”, to deduce the theory of weakening, to abstract the concept of animation and combine with learning. The key content to achieve dynamic, refined. Visualization teaching is the completion of teaching tasks, improve teaching quality, but also stimulate students interest in learning and application of ability.
