摘要
本文阐述了信号调制定理和时域抽样定理的内容,并对二者的理论实质进行了对比分析,指出抽样是广义调制和调制是特殊的抽样两个观点。同时,我们以此为基础提出"信号与系统"课程教学中,关于调制定理与抽样定理的对比教学,这有利于学生理解二者的实质。
Modulation theorem and continuous-time signal sampling theorem are explained and the essence of them is analyzed in detail.Two ideas are given that sampling is general modulation and modulation is special case of sampling.Based on the new ideas,contrast teaching methodology of modulation theorem and continuous-time signal sampling theorem is given when teaching Signal and System course,which is helpful for students to understand them deeply.
