基于MATLAB GUI及三维图形视角变化制作信号与系统课件

摘要

基于MATLAB GUI的软件平台进行信号与系统课件制作,以周期方波信号的分解为具体实例,详细地论述了课件制作过程,通过调整输入参数,进行人机动态图形画面交互,并用三维立体图形及其视角变化构建了谐波信号的时域特性和频域特性之间的映射关系,顺利地过渡到频谱分析.%The paper introduces courseware of signal and system design based on MATLAB GUI,It takes analysis of period square wave signal for example to discuss the course of courseware design.Then, Make person-computer graph mutually by adjusting parameter, and construct time-frequency relation of sine wave signal through three-dimensional graph and angle of view variety.In the end, it transits to analysis of frequency successfully.
