摘要/Abstract

摘要： 《信号与系统》课程教学上的困难源于数学知识、物理概念和工程背景等多个环节的相互渗透和多重叠加效应. MATLAB 软件强大的数据处理及直观化的图形显示功能有助于开展多维互动式的课堂教学,增强学生的学习积极性和主动性,其快速上手可以从几个核心知识点的MATLAB仿真开始.借助带通滤波器的一个典型例题讲述频谱、系统函数、零状态响应、根轨迹等关键问题求解的MATLAB实现,给出了在《信号与系统》课程教学中应用MATLAB仿真软件时一般应具有的主要环节和步骤.

关键词: MATLAB, 信号与系统, 带通滤波器

Abstract: The difficulties in the teaching of The Course Signals and Systems stem from the mutual penetration and multiple superposition effects of multiple links such as mathematical knowledge, physics concepts, and engineering background. The powerful data processing and intuitive graphical display of MATLAB help perform multi-dimensional interactive teaching and enhance students’ learning enthusiasm and initiative and its quick master can be started from MATLAB simulation of several core points. A typical example of a band-pass filter is used to describe the MATLAB implementation of solving key problems such as frequency spectrum, system function, zero-state response, and root locus, and give out the main steps that the MATLAB simulation should generally be used in the teaching of The Course Signals and Systems.

Key words: Matlab, The Course Signals and Systems, band pass filter
