【摘要】 本文针对信号时域抽样的阐述进行了研究与探索,提出从信号的时域与频域分析的角度引入信号的时域抽样,具有数学概念和物理概念更加清晰的特点,且与工程实际更加符合,克服了传统方法的不足,易于教师的教学和学生的理解,也有利于学生深刻理解信号的时域分析与频域分析之间的内在联系。更多还原

【Abstract】 The description methods of signal sampling are studied in this paper.We propose to introduce sampling from time-domain and frequency-domain analysis.This method not only has clearer mathematical and physical concept,but is more close to the practical applications.It overcomes some of the disadvantage of traditional method and is helpful for students to understand the inter-relationship between time-domain and frequency-domain analysis.更多还原
