正弦信号激励下的二阶电路

The Second order circuit stimulated by sine signal

对于二阶电路,换路时一般要经历一个暂态过程,本文通过拉普拉斯变换及其逆变换对二阶电路的暂态过程进行了研究,并据此推导出二阶电路换路时不经暂态过程而直接进入稳态的条件。

Commonly, second order circuit would experience a transient process when it is switched. It is studied that the transient process of second order circuit by Laplace transform and Laplace inverse transform. And the condition is deduced that second order circuit enter the steady state directly without experiencing the transient process when it is switched.
