Frequency Response
Note 27. The passband and stopband frequencies scale with fs (system sampling rate).
Note 28. The calculated delay time caused by digital filtering. This time is from setting the 16-bit data of both channels
Note 29. These frequency responses scale with fs. If a high-level and low frequency signal is input, the analog output clips
