Comparison of Butterworth and Chebyshev Filters - IIR Filters

on
Properties of Butterworth Filter:.
  • The Magnitude response of the filter decreases monotonically as the frequency increases from 0.
  • The normalized poles lie on the circle
  • Higher order Filter
  • It has more transition band compared to Chebyshev Filter
  • More number of poles required to design this filter
Properties of Chebyshev Filter:.
  • The Magnitude response of the filter exhibits ripples in the passband or stopband based on the type of filters.
  • The normalized poles lie on tan ellipse
  • Lower order Filter
  • It has less transition band compared to Butterworth Filter
  • Less number of poles required to design this filter
