Figure 8-37 shows the magnitude response and Figure 8-38 shows the pass-band ripple and phase deviation for a decimation filter with a sampling rate of 16 kHz or 14.7 kHz. Table 8-31 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 0.451 × fS||–0.05||0.05||dB|
|Stop-band attenuation||Frequency range is 0.61 × fS onwards||87.3||dB|
|Group delay or latency||Frequency range is 0 to 0.363 × fS||7.6||1/fS|
|Group delay deviation||Frequency range is 0 to 0.363 × fS||–0.022||0.022||1/fS|
|Phase deviation||Frequency range is 0 to 0.363 × fS||–0.21||0.25||Degrees|
