Note: 12. The passband and stopband frequencies scale with fs (system sampling rate).
ex.) PB=0.4535×fs (@
±
0.05dB), SB=0.546×fs.
Note: 13. The calculating delay time which occurred by digital filtering. This time is from setting the 16/18bit data of
both channels to input register to the output of analog signal.
