| 摘 要： | 为了深刻理解信号与系统理论,文章着重分析了离散信号与系统理论中的分解思想,即将复杂的信号分解为简单的信号,从而使复杂问题简单化;根据数学分析之方法,当采用不同的基本信号时,便形成了信号分析中的时域分析、频域分析和复频域分析几种理论;从方法论角度而言,信号分析理论实质上体现了复杂对象的合理＂拆分＂与有机＂整合＂,体现了以不同的视角及系统论的观点分析问题、解决问题的思想主线。

| Abstract: | In order to deeply understand the theory of signal and system,the paper focuses on analyzing decomposition thought in discrete signal and the system-theory,which means decomposing complex signal into simple signal,so as to simplify the complex problems;according to the method of mathematical analysis,when apply different basic signal,it will form several theories of signal analysis,such as time-domain analysis,frequency domain analysis,and complex frequency domain analysis;from the perspective of methodology,the theory of signal analysis virtually reflects the reasonable "Resolution" and organic "Integration" of complex object,and reflects the ideological line of analyzing and solving the problems through different perspectives and systematic view. |
