Figure 8-59 shows the magnitude response and Figure 8-60 shows the pass-band ripple and phase deviation for a decimation filter with a sampling rate of 192 kHz or 176.4 kHz. Table 8-42 lists the specifications for a decimation filter with a 192-kHz or 176.4-kHz sampling rate.

|Stop-band attenuation||Frequency range is 0.6 × fS onwards||85.6||dB|
|Group delay or latency||Frequency range is 0 to 0.085 × fS||3.7||1/fS|
|Group delay deviation||Frequency range is 0 to 0.085 × fS||–0.024||0.024||1/fS|
|Phase deviation||Frequency range is 0 to 0.085 × fS||–0.12||0.18||Degrees|
