Elliptic Cauer Filter Formula, Equations, & Calculations
- the basic calculations formulae and equations for the Cauer / Elliptic filter
The calculations for the elliptic filter of Cauer filter are a little more complicated than those for many other forms of filter.
There are a number of Cauer / elliptic filter calculations and equations.
Elliptic filter gain equation
The equation for the gain of a low-pass elliptic or Cauer filter as a function of angular frequency ω is given by:
Rn is the nth-order elliptic rational function
ω is the frequency of the response in radians
ωo is the cut-off frequency in radians
ε is the ripple factor
ξ is the selectivity factor
