【摘要】 信号的抽取与插值是改变信号抽样率最基本的方法,是数字信号处理等相关课程的重点内容。在对抽取与插值理论详细阐述基础上,利用MATLAB的图形用户界面GUI设计了信号抽取与插值的实验仿真系统。实践表明,此设计能有效辅助课堂教学和实验教学,使学生能更好地理解该部分基本理论,并锻炼了工程应用能力。更多还原

【Abstract】 Signal decimation and interpolation is the most basic method for signal resample,and is an important content in the course of digital signal processing and other related courses.On the basis of describing the theory of signal decimation and interpolation in detail,an experiment simulation system is designed based on the graphical user interface of Matlab.The practice indicates that the experiment simulation system can assist us in classroom teaching and experiment teaching,make students better understand and master the basic theory of the course,and also can improve the students’ engineering application ability.更多还原
