Time and Frequency Response
Five graphs displaying attenuation versus frequency curves for filter orders up
to ten are given in Figures 2.13 to 2.17. The graphs are for Chebyshev filters
with a passband ripple of 0.01 dB, 0.1 dB, 0.25dB, OSdB, and 1 dB, respectively.
In each case a 3dB cutoff point is used.
