Figure 8-41 shows the magnitude response and Figure 8-42 shows the pass-band ripple and phase deviation for a decimation filter with a sampling rate of 32 kHz or 29.4 kHz. Table 8-33 lists the specifications for a decimation filter with a 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 0.368 × fS||8.7||1/fS|
|Group delay deviation||Frequency range is 0 to 0.368 × fS||–0.026||0.026||1/fS|
|Phase deviation||Frequency range is 0 to 0.368 × fS||–0.26||0.31||Degrees|
