摘要
线性卷积与周期卷积是数字信号处理技术的核心概念,深入理解它们在时域与频域的内在联系非常重要。本文针对课程教学中存在的实际问题,提出了基于线性卷积-周期卷积概念体系结构的教学方法,系统阐述了概念内涵及相互联系,简要给出了开展教学工作的注意问题、实施过程以及教学效果。本文提出的基于概念体系结构的教学方法,有助于学生建立“数字信号处理”知识体系、提高分析问题的能力与逻辑思维能力。
Linear convolution and periodic convolution are the core concepts of digital signal processing technology.It is very important to deeply understand their internal connection in the time and frequency domains.Aiming at the practical problems in the course teaching,this paper proposes a teaching method based on the concept system of linear convolution and periodic convolution,systematically expounds the connotation and interrelationship of the concepts,and briefly gives the matters needing attention,implementation process and teaching effect in teaching.The teaching method based on the concept system proposed in this paper is helpful for students to establish the knowledge system of"Digital Signal Processing"and improve their ability to analyze problems and logical thinking.
