Notes:
1. Idle channel, digital input all zeros.
2. Combined digital and analog filter characteristics.
3. The passband and stopband edges scale with frequency. For input word rates, IWR, other than
48 kHz, the 0.00025 dB passband edge is 0.45×IWR and the stopband edge is 0.55×IWR.
4. Digital filter characteristics.
