Notes: 7. The passband and stopband frequencies scale with fs (system sampling rate).

For example, PB=0.4535×fs (@

±0.05dB), SB=0.546×fs.

8. 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.
