It is also the simplest (first-order) low-pass filter. We'll analyze only the first circuit; the second is very similar. == Transfer function == A transfer ratio is a gain factor for the sinusoidal input signal with given frequency. A transfer function shows the dependence of the transfer ratio from the signal frequency, given that the input signal is sinusoidal. According to Ohm's law, $Y=X\backslash frac=X\backslash frac\}+R\}=X\backslash frac,$ where $X$ and $Y$ are input and output signals' amplitudes respectively, and $Z\_R$ and $Z\_C$ are the resistor's and capacitor's impedances. Therefore, the complex transfer function is $K(j\; \backslash omega)=\backslash frac=\backslash frac\},$ where $\backslash omega\_0=\backslash frac.$ Amplitude transfer function $H(\backslash omega)=|K(j\; \backslash omega)|=\backslash frac\backslash right)^2\}\}.$ Phase transfer function $\backslash phi\; (\backslash omega)=\backslash arg\; K(j\; \backslash omega)=-\backslash arctan\; \backslash frac.$ Transfer functions for the second circuit are the same (with $\backslash omega\_0=\backslash frac$). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Passive integrator circuit」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
