Note 17. The passband and stopband frequencies scale with fs (sampling frequency).
For example, PB=0.454 x fs (@ -1.0dB).
Note 18. The calculated delay time caused by digital filtering. This time from the input of an analog signal to setting the
20bit data of both channels to the output register of the ADC and includes the group delay of the HPF.
