Measurement Bandwidth = 20 to Fso/2 Hz, and Word Width = 32-Bits, unless otherwise stated.)

DIGITAL FILTER CHARACTERISTICS

Notes: 3. The equation for the group delay through the sample rate converter is (56.581 / Fsi) + (55.658 / Fso).

For example, if the input sample rate is 192 kHz and the output sample rate is 96 kHz, the group delay

through the sample rate converter is (56.581/192,000) + (55.658/96,000) =.875 milliseconds.
