Chebyshev Type I filters are equiripple in the passband and monotonic in the stopband. The poles are evenly spaced about an ellipse in the left half plane. The Chebyshev Type I passband edge angular frequency ω0 is set to 1.0 for a normalized result. This value is the frequency at which the passband ends. The filter has a magnitude response of 10–Rp/20.
The transfer function is given by
