Butterworth IIR Filters
Butterworth filters are the most popular version of IIR analog filters.
These filters are also known as “maximally flat” because they have no
passband ripple. Additionally, they have a monotonic response in both
the stopband and the passband. Butterworth filters trade-off roll off
steepness for their no ripple characteristic. The distinguishing
Butterworth filter feature is its poles are arranged in a uniquely
symmetrical manner along a circle in the s-plane. The expression for the
Butterworth filter’s magnitude-squared function is as follows:
where:
The filter’s cutoff characteristics become sharper as N increases. If a
substitution is made such that j = s, then the following equation is
derived:
