PRODUCTION DATA
Figure 7-25 and Figure 7-26 respectively show the magnitude response and the pass-band ripple for a decimation filter with a sampling rate of 29.4 kHz to 32 kHz. Table 7-22 lists the specifications for a decimation filter with a 29.4-kHz to 32-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 | 73.7 | dB | ||
Frequency range is 4 × fS onwards | 107.2 | ||||
Group delay or latency | Frequency range is 0 to 0.454 × fS | 16.9 | 1/fS |
