Note: 1. The passband and stopband frequencies scale with fs.
2. The calculating delay time which occurred by digital filtering. This time is from the input of
analog signal to setting the 16bit data of both channels to the output register of ADC.
For DAC, this time is from setting 16bit data of both channels on input register to the output of
analog signal.
