Note:5. The passband and stopband frequencies scale with fs (sampling frequency).
For examples, PB=0.454 x fs(@ADC: -1.0dB), PB=0.454 x fs(@DAC: -0.1dB).
Note: 6. The calculating delay time which occurred by digital filtering. This time is from the input of analog signal to
setting the 20bit data of both channels to the output register for ADC and include group delay of HPF.
