Figure 8-39 shows the magnitude response and Figure 8-40 shows the pass-band ripple and phase deviation for a decimation filter with a sampling rate of 24 kHz or 22.05 kHz. Table 8-32 lists the specifications for a decimation filter with a 24-kHz or 22.05-kHz sampling rate.
|Pass-band ripple||Frequency range is 0 to 0.459 × fS||–0.01||0.01||dB|
|Stop-band attenuation||Frequency range is 0.6 × fS onwards||87.2||dB|
|Group delay or latency||Frequency range is 0 to 0.365 × fS||7.5||1/fS|
|Group delay deviation||Frequency range is 0 to 0.365 × fS||–0.026||0.026||1/fS|
|Phase deviation||Frequency range is 0 to 0.365 × fS||–0.26||0.30||Degrees|
