关于一阶电路时间常数求法的讨论

Determination of Time Constant on First Order Circuit

电路时间常数是一阶电路分析中的重要概念,它决定了一阶电路的响应特性。本文总结了时间常数的一般计算方法,并对多个动态元件和/或多个电阻元件构成的一阶电路、含运算放大器的一阶电路、含全耦合电感元件的一阶电路等三类电路讨论了时间常数的计算方法。

Time constant is an important concept in analysis of first order circuit and it determines the response characteristic of first order circuit. Determination methods of time constant are summarized. Aiming at three types of first order circuits that include more than one resistor and/or dynamic element, operating amplifier, wholly cou- pled inductor respectively, calculation of time constant is discussed.
