ANALOG CHARACTERISTICS (CONTINUED)

Notes: 7. The passband and stopband edges scale with frequency. For input word rates, Fs, other than 48 kHz,

the 0.01 dB passband edge is 0.4535x Fs and the stopband edge is 0.5465x Fs.

8. Digital filter characteristics.

9. Measurement bandwidth is 10 Hz to 3 Fs.
