cours.polymtl.caterworth, Chebyshev et Bessel. La figure ci-contre illustre ces types. La première, Butterworth, est optimisée pour une bande passante la plate pos-sible. Pour sa part, la carac-téristique Chebyshev met à profit les pentes accentuées des filtres du second ordre à fort « Q » pour produire des débuts de zone de coupure plus raides.

This is accomplished by substituting the frequency-domain transfer function H(s) with one of the relevant frequency transformations listed below.
