Filter Characteristics
The analog filter is a 2nd-order Butterworth filter, with a cutoff frequency that is about 1.2 times the aliasing
frequency (1/2Fs).
The digital filter attenuation characteristics are about -6 dB at 1/2Fs. The input amp and output amp are
both added for the input signal, so (as shown in the following diagram) the attenuation is about -12 dB at an
aliasing frequency (1/2 Fs).
