Detailed Description

Template Class for 1st Order high pass IIR filter from S-domain transformation.

Template for 1st Order IIR filter.

The filter is assumed the first order high pass digital filter generated by the bilinear transform of a first order analog filter.

$H(s) = \frac{s}{(s+A)}$

$H(z) = \frac{A*(1+z^-1)}{((A-1)+(A-1)*z^-1)}$ where A is real
