Hi,
I am using the Biquad Filter Design Tool in the PurePath Studio. I choosed the Equalizer(Q factor) filter. Then I set the Fc, Gain, Q as shown in Fig.1
Applying the equations in section 1.2 of Biquad Filters Application Note.pdf, I computed five biquad coefficients –b0, b1, b2, a1, a2 – , but the results is different from the results given by the PPS Bi-quad tool which is listed as follows, I want to know the reason.
