Difference of AIC3254 Biquad difference?

Hi, Roman,

All the differences between these components are on the coefficients. The Biquad_1 doesn't have additional coefficients. It just has 5 24-bits coefficients (A1, A2, B0, B1, B2) that need to be configured. Then, the Biquad_ext_1 is similar to the Biquad_1 but it has extended coefficients. I mean, it has 48-bits coefficients (A1, A2, B0, B1, B2) for a high precision. Finally, the Biquad_Eq_1 is similar to the Biquad_1 but it also supports 5 EQ Scaling coefficients.

Hi Luis,

Understand, but what means scaling coefficients in Biquad_Eq_1? How to configure it?

Hi, Roman,

These parameters allow to change the scale (linear) parameter of the Biquad GUI in runtime.

This parameter is included on all the biquad blocks. However, the Biquad_Eq_1 block allows its configuration in real time.
