Figure 44 and Figure 45 respectively show the magnitude response and the pass-band ripple for a decimation filter with a sampling rate of 8 kHz or 7.35 kHz. Table 20 lists the specifications for a decimation filter with an
8-kHz or 7.35-kHz sampling rate.
|Pass-band ripple||Frequency range is 0 to 0.454 × fS||–0.05||0.05||dB|
|Stop-band attenuation||Frequency range is 0.58 × fS to 4 × fS||72.7||dB|
|Frequency range is 4 × fS onwards||81.2|
|Group delay or latency||Frequency range is 0 to 0.454 × fS||17.1||1/fS|
