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.
