Notes/Equations
- This is an S-domain filter.
- Poles and Zeros are a list of complex pole/zero locations.
The transfer function for the filter is:
where
S = j(Freq / Fpass)
and
Freq is the analysis frequency
At least one pole must be supplied. - For information on lowpass filter behavior at DC, refer to Lowpass Filter Behavior at DC.
