Note 8. The passband and stopband frequencies scale with fs. For example, PB (±0.02dB) at fs=48kHz is 0.4535 × fs. The
reference frequency of these response is 1kHz.
Note 9. The calculated delay time induced by digital filtering. This time is from the input of an analog signal to the setting
of 24bit data both channels to the ADC output register for ADC.
