PRODUCTION DATA
Figure 8-15 and Figure 8-16 respectively show the magnitude response and the pass-band ripple for a decimation filter with a sampling rate of 48 kHz or 44.1 kHz. Table 8-12 lists the specifications for a decimation filter with an 48-kHz or 44.1-kHz sampling rate.
PARAMETER | TEST CONDITIONS | MIN | TYP | MAX | UNIT |
---|---|---|---|---|---|
Pass-band ripple | Frequency range is 0 to 0.454 × fS | –0.05 | 0.05 | dB | |
Stop-band attenuation | Frequency range is 0.58 × fS to 4 × fS | 73.8 | dB | ||
Frequency range is 4 × fS onwards | 98.1 | ||||
Group delay or latency | Frequency range is 0 to 0.454 × fS | 17.1 | 1/fS |
