Note 13. The passband and stopband frequencies scale with fs. For example, PB = 0.4535Ãfs (@±0.01dB), SB =
0.546Ãfs.
Note 14. 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.
