Figure 8-53 shows the magnitude response and Figure 8-54 shows the pass-band ripple and phase deviation for a decimation filter with a sampling rate of 32 kHz or 29.4 kHz. Table 8-39 lists the specifications for a decimation filter with an 32-kHz or 29.4-kHz sampling rate.
|Pass-band ripple||Frequency range is 0 to 0.457 × fS||–0.04||0.04||dB|
|Stop-band attenuation||Frequency range is 0.6 × fS onwards||88.3||dB|
|Group delay or latency||Frequency range is 0 to 0.325 × fS||5.2||1/fS|
|Group delay deviation||Frequency range is 0 to 0.325 × fS||–0.492||0.492||1/fS|
|Phase deviation||Frequency range is 0 to 0.325 × fS||–9.5||13.5||Degrees|
