Note 10. The passband and stopband frequencies scale with fs (system sampling rate). Each response refers to that of
1kHz.
Note 11. A calculating delay time which induced by digital filtering. This time is from the input of an analog signal to
the setting of 24-bit data of both channels to the ADC output register.
Note 12. The passband and stopband frequencies scale with fs (system sampling rate). Each response refers to that of
1kHz.
Note 13. A calculating delay time which induced by digital filtering. This time is from setting the 24-bit data of both
channels to input register to the output of analog signal.
