| Abstract: | Determination of the time constant of the RC integrator circuit is a difficult point in the first-order RC circuit response testing experiments. It is very difficult to detect the RC time constant through conventional methods. For this problem, this paper gives an experimental method for measuring time constant of the RC integrator circuit, which uses the proportional relationship between the amplitude of the signal source and the voltage across the capacitor to solve the problem that the time constant can＆#39;t be measured through conventional methods in the RC integrator circuit output waveform diagram. The experimental results show that： the time constant measured through this method is close to the theoretical value with the relative error less than 10%. The method is simple and practical and provides reference for the time constant estimation of the first-order RC integrator circuit. |
