【摘要】 一阶RC电路在方波激励下的时域响应会随着电路参数的变化、电路输出的不同表现出不同的特性。当时间常数远远大于或小于方波脉冲宽度时,电路时域响应会分别表现出积分电路或微分电路的特性。本文对这两种情况下电路的时域响应分别进行了详细讨论,并给出了输出的变化规律,接着讨论了进行这两种电路实验时应该注意的问题,最后对学生做实验过程中容易出现的错误进行了说明。更多还原

【Abstract】 The time-domain responses of first-order RC circuit under square wave excitation exhibit various characteristics when circuit parameters change or circuit output variables are different.The time-domain response characteristics of integral circuit or differential circuit is shown when time constant of the circuit is much larger than or much less than square wave pulse width.The paper in detail discussed the RC circuit time-domain responses in the two cases.The changed regulations of the circuit outputs are also given.Then problems needing attention when doing the experiments of two circuits are discussed.At last some easily emerging errors were illuminated when students doing the experiments.students更多还原
