Note 11. The passband and stopband frequencies scale with fs(system sampling rate). For example, PB=0.4535×fs
(@±0.05dB), SB=0.546×fs.
Note 12. The calculating delay time which occurred by digital filtering. This time is from setting the 16/24bit data of
both channels to input register to the output of analog signal.
