摘要
在传统的RC串联电路稳态特性实验基础上,提出包含RC低通、高通、带通、带阻、以及全通滤波电路的实验方案设计。实验采用示波器和相位计直接测量输入输出信号的幅值及相位差。测得各种RC滤波电路幅频特性及相频特性并和理论计算曲线相比较。
Based on the experiment of the steady state characteristic of the traditional RC series circuit, we proposed the experimental scheme design of steady state characteristics including RC low-pass, high-pass, bandpass, band-hinder, and all-pass filter circuit.We used the oscilloscope and the phase meter to measure the amplitude and phase difference of the input and output signals. The amplitude-frequency and phase-frequency characteristics of the RC filter circuits were measured and compared with the theoretical calculation curves.
