High-Precision, Second-Order Biquad Filter Structure
The TAS3001 has six cascaded biquad filters for the left and right channels to permit parametric equalization and
filtering of the input signal. Each biquad is able to specify a wide variety of first- and second-order filter types, including
high-pass, low-pass, band-pass, band-block, notch, and all-pass filter types. Examples of a few of the filters that can
be implemented by the TAS3001 shapes are illustrated in Figure 12 though Figure 16.
