摘要
"信号与系统"课程中理论和方法较多,其中一个重要的思想就是分解,即将复杂的对象分解为简单的对象,从而使复杂问题简单化;由于所采用基本分解单元信号的不同,分别形成了时域分析理论、频域分析理论和复频域分析理论,这些理论实质上体现了以多视角观察和分析问题,进而解决问题的思想。深刻理解该课程中的这种方法论思想,不仅对学好"信号与系统"课程大有裨益,而且对培养和造就高素质人才也具重要意义。
There are many theories and methods in Signals and Systems course. One of the important ideas is resolution, i. e. resolving complicated thing into simple ones. Thereby it changes complicated problem into simple ones. Due to the difference in adopted basic resolution unit signals, analytic method of time field, frequency field and complex frequency field are formed respectively. Virtually the methods embody the thought that studying problems with diverse angles of view, and analyzing problems, moreover solving problems. Profoundly comprehending the methodology thought has a great benefit to well study signals and systems, and has vital significance to train and bring up high quality students.
