User Programmable Filters
Depending on the selected processing block, different types and orders of digital filtering are available. A
first-order IIR filter is always available, and is useful to efficiently filter out possible DC components of the
signal. Up to 5 biquad section or alternatively up to 25-tap FIR filters are available for specific processing
blocks. The coefficients of the available filters are arranged as sequentially indexed coefficients in Page 4.
The coefficients of these filters are each 16-bits wide, in twos complement and occupy 2 consecutive 8-bit
registers in the register space. For default values please see the Register Map section.
5.8.3.1
First-Order IIR Section
The transfer function for the first-order IIR Filter is give by:
(2)
The frequency response for the first-order IIR section with default coefficients is flat at a gain of 0 dB.
