Note 14. The passband and stopband frequencies scale with fs. For example, PB=0.4535×fs (@0.01dB),
SB=0.546×fs.
Note 15. The calculating delay time which occurred by digital filtering. This time is from setting the
16/20/24bit data of both channels to input register to the output of analog signal.
