You need to find out jf the system is LTI system or not. If it is, it’s
simple. The impulse response describes everything.
If it is not LTI, then you might have time variant linear system, or time
invariant nonlinear system or time variant nonlinear system. There are ways
to deal with some of the cases.

项长中国人志气的重要发明"。该成果广泛应用于我国多种军用航空发动机中,取得了
数以亿元计的经济效益,至今仍保有先进水平。本刊记者于今年10月采访了高歌教授,
了解到了他近期从事的一些前沿科研工作的最新进展,尤其是他对龙卷风的研究及其工
程应用价值,让人耳目一新。
高歌教授在采访中提到,传统的航空发动机技术虽然还在不停地改进提高之中,但
受到原理和材料工艺上的限制,已经逐渐逼近了性能发... 阅读全帖
