摘要
通过实验观察不同电阻值时一阶RC微分电路的输出波形图,本文分析了当电阻改变从而引起了时间常数τ的变化时,对该输出波形图的影响及产生此变化的原因。
Through experimental observation of different resistance value of first-order RC differential circuit output waveform, this paper analyzes the resistance change when caused the time-constant ＂rchanges, the output waveform and the effect of the change reason.
