 This  block is implemented as a biquad filter that has multiple sets of coefficients stored in tables on the DSP. See [[resources/tools-software/sigmastudio/toolbox/algorithminformation/general2ndorderfilters|General 2nd-Order Filters]] (in Algorithm Information) for details about the biquad filter design techniques used for this block.\\ This  block is implemented as a biquad filter that has multiple sets of coefficients stored in tables on the DSP.
