8. The calculating delay time which occurred by digital filtering. This time is from the input of analog signal to
9. fs=96kHz.
setting the 24bit data of both channels to the output register for ADC.
For DAC, this time is from setting the 24bit data of both channels on input register to the output of analog
signal.
The reference frequency of these responses is 1kHz.
