Notes/Equations
  1. This is an S-domain filter.
  2. 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.
  3. For information on lowpass filter behavior at DC, refer to Lowpass Filter Behavior at DC.
