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 filter out possible dc components of the signal
efficiently. Up to five biquad sections or, alternatively, FIR filters of up to 25 taps are available for specific
processing blocks. The coefficients of the available filters are arranged as sequentially indexed
coefficients.
