Transfer Function

$\text{Full Wave} \\ V_{out} = \pm G \cdot \lvert V_{in} \rvert \\~\\ \text{Positive Half Wave} \\ V_{out} = \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_{out} = \begin{cases} 0 & \text{if $\> V_{in} > 0$} \\ \pm G \cdot V_{in} & \text{if $\> V_{in} < 0$} \end{cases}$
