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。
為瞭深刻理解信號與繫統理論,文章著重分析瞭離散信號與繫統理論中的分解思想,即將複雜的信號分解為簡單的信號,從而使複雜問題簡單化;根據數學分析之方法,噹採用不同的基本信號時,便形成瞭信號分析中的時域分析、頻域分析和複頻域分析幾種理論;從方法論角度而言,信號分析理論實質上體現瞭複雜對象的閤理＂拆分＂與有機＂整閤＂,體現瞭以不同的視角及繫統論的觀點分析問題、解決問題的思想主線。

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 anal- ysis, frequency domain analysis, and complex frequency domain analysis ; from the perspective of methodolo- gy, 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 per- spectives and systematic view.
