LTI连续时间系统零状态响应的求解方法

The methods of zero-state response of LTI continuous system

目前国内很多"信号与系统"的教材中讨论了LTI连续时间系统零状态响应的一些求解方法,本文根据现有的信号与系统教材中连续时间系统零状态响应的求解方法,分别从利用冲激响应与激励的卷积、微分方程和变换域三方面求解零状态响应,并给出了实例说明了其正确性。

The method of zero-state response of LTI continuous system are discussed in most of ＂ signal and system＂ textbook. In this paper, three methods are discussed to solve zero-state response according to existing the methods of zero-state response of LTI continuous system in ＂signal and system＂ textbooks. The three methods are present from the angles of the convolution of the unit impulse response and the input given signal , the differential equation and the transform domain. In order to demonstrate the validity of methods, some examples are shown in detail.
