Line 45: Alternative methods include the [[bilinear transform]] and [[impulse invariance]] methods. [[File:Chebyshev_responses.svg\|left\|thumb\|350px\|Responses of the filter (dashed), and its discrete-time approximation (solid), for nominal cutoff frequency of 1 Hz, sample rate 10 Hz. The discrete-time filter does not reproduce the Chebyshev equiripple property in the stopband due to the interference from cyclic copies of the ~~passband~~response.]] ==References==
