SLASEG6B May 2018 – June 2020 TAS3251
The device supports up to 15 individual tuned PEQs for left channel and up to 15 individual tuned PEQs for the right channel. The PEQs are implemented using cascaded “direct form 1” BQs structures as shown in Figure 43.
All BQ coefficients are normalized with a0 to insure that a0 is equal to 1. The structure requires 5 BQ coefficients as shown in Table 27. Any BQ with coefficients greater than 1 undergoes gain scaling as described in BQ Gain Scale.
|BQ COEFFICIENT FOR TAS3251||COEFFICIENT CALCULATION|
|B0_DSP||b0 / a0|
|B1_DSP||b1 / (a0 × 2)|
|B2_DSP||b2 / a0|
|A1_DSP||–a1 / (a0 × 2)|
|A2_DSP||–a2 / a0|
