摘要
“数字信号处理”的经典课程体系以“系统”为中心,以离散时间傅立叶变换、z变换和离散傅立叶变换为分析工具,以滤波器设计为目的,注重定理和公式推导及其性质分析,这种教学模式很难让学生建立一个形象、完整统一的知识体系框架。从几何视角将“系统”化和“代数”化的经典课程体系重构为面向“信号”的“几何”知识体系,从而提升学生对本质问题的洞察力,帮助学生建立系统的知识体系。
Targeting at filter design,the classical curriculum framework of Digital Signal Processing is centered on the system,with discrete-time Fourier transform,z-transform and discrete Fourier transform as analysis tools.It emphasizes the derivation of theorems and formulas and the analysis of their properties,which is complicated for students to establish a comprehensive knowledge framework.From the perspective of geometry,this paper reconstructs the classical curriculum system that is“system”and“algebraic”-oriented into a“geometric”knowledge system oriented to“signals”,thereby enhancing students′“insight”on essential issues and establishing a systematic knowledge framework.
