14. The passband and stopband frequencies scale with fs.
15. The calculating delay time which occurred by digital filtering. This time is from setting the input of analog signal to
16. 40.0kHz; fs=96kHz , 80.0kHz; fs=192kHz.
For example, 21.8kHz at –0.1dB is 0.454 x fs.
setting the 24bit data of both channels to the output register for ADC.
For DAC, this time is from setting the 20/24bit data of both channels on input register to the output of analog
signal.
