Low-frequency Variant

FilterLowpassLF : a version of this module that uses additional hardware resources to extend its low-frequency range.

Transfer Function

$$ \frac{V_{out}(s)}{V_{in}(s)} = \pm \frac{2\pi f_cG}{s + 2\pi f_c} $$

Analog Resource Usage

$$ \begin{array}{|c|c|} \hline \text{Opamps} & \text{1 of 8} \\ \hline \text{Capacitors} & \text{3 of 32} \\ \hline \end{array} \\~\\ \text{Low Frequency Variant:} \\ \begin{array}{|c|c|} \hline \text{Opamps} & \text{1 of 8} \\ \hline \text{Capacitors} & \text{4 of 32} \\ \hline \end{array} $$
