Channel Cut-off Frequency
The filter cut-off frequency, -3 dB, is the point on the frequency response curve
where frequency components of the input signal are passed with 3 dB of
attenuation. This table shows cut-off frequencies for the supported filters.
All input frequency components at or below the cut-off frequency are passed by
the digital filter with less than 3 dB of attenuation. All frequency components
above the cut-off frequency are increasingly attenuated as shown in the graphs on
page 49 .
