Figure 8-49 shows the magnitude response and Figure 8-50 shows the pass-band ripple and phase deviation for a decimation filter with a sampling rate of 16 kHz or 14.7 kHz. Table 8-37 lists the specifications for a decimation filter with a 16-kHz or 14.7-kHz sampling rate.
|Pass-band ripple||Frequency range is 0 to 0.45 × fS||–0.05||0.05||dB|
|Stop-band attenuation||Frequency range is 0.6 × fS onwards||87.2||dB|
|Group delay or latency||Frequency range is 0 to 0.325 × fS||4.3||1/fS|
|Group delay deviation||Frequency range is 0 to 0.325 × fS||–0.512||0.512||1/fS|
|Phase deviation||Frequency range is 0 to 0.325 × fS||–10.0||14.2||Degrees|
