6 / 32 page CS4228A 6 ANALOG CHARACTERISTICS (Continued) 8. The passband and stopband edges scale with frequency. For input word rates, Fs, other than 44.1 kHz, the 0.01 dB passband edge is 0.4535×Fs and the stopband edge is 0.5465×Fs. 9. Digital filter characteristics. 10. Measurement bandwidth is 10 Hz to 3 Fs.
