Note 12. The passband and stopband frequencies scale with fs. For example, PB=0.4535×fs (@±0.01dB), SB=0.546×fs.
Note 13. The calculating delay time which occurred by digital filtering. This time is from setting the 16/20/24/32bit data
MS1146-E-03
of both channels to input register to the output of analog signal.
