2%, the filter response is shifted by the ratio of switched-capacitor filter clock frequency to
288 kHz.
11. The filter gain outside of the pass band is measured with respect to the gain at 1 kHz. The filter gain within the pass band is measured
with respect to the average gain within the pass band. The pass bands are 300 to 3400 Hz and 0 to 3400 Hz for the band pass and
low-pass filters respectively.
