Transfer Function
$$
\text{Full Wave} \\
V_{rec} = \pm G \cdot \lvert V_{in} \rvert \\~\\
\text{Positive Half Wave} \\
V_{rec} =
\begin{cases}
\pm G \cdot V_{in} & \text{if $\> V_{in} > 0$} \\
0 & \text{if $\> V_{in} < 0$}
\end{cases} \\~\\
\text{Negative Half Wave} \\
V_{rec} =
\begin{cases}
0 & \text{if $\> V_{in} > 0$} \\
\pm G \cdot V_{in} & \text{if $\> V_{in} < 0$}
\end{cases} \\~\\
\frac{V_{out}(s)}{V_{rec}(s)} = \pm \frac{2\pi f_cG}{s + 2\pi f_c}
