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
