从信号分解的角度看线性时不变系统的分析

The Linear Time-invariant Systems Anaysis Based-on Decomposing Signals

本文利用线性时不变系统本身的特性 ,从信号分解的角度详细论述了线笥时不变系统的时域、频域及复频域分析方法 ,得到了与数字变换方法相同的结果。利用这种分析思路 ,可以将线性系统的不同分析方法有机地结合在一起 ,同时可以获得多种系统概念的物理解释 。

Using linear time-invariant(LTI) systems characteristic in this paper, we discuss LTI systems analysis methods in time-domain, in frequency-domain and in complex frequency-domain in detail, obtain the same results as mathematic transforms. We can combine different methods into an organic part and obtain physical explaining about systems concepts. It can be used as reference to understand LTI systems analysis.
