Note 28. The passband and stopband frequencies scale with fs (system sampling rate).
For example, ADC is PB=0.454*fs (@-1.0dB), DAC is PB=0.454*fs (@-0.1dB).
Note 29. The calculated delay time caused by digital filtering. This time is from the input of an analog signal to setting the
16bit data of both channels to the output register of the ADC and includes the group delay of the HPF.
For DAC, this time is from setting the 16bit data of both channels on input register to the output of analog signal.
Note 30. DAC
