does ADAU1452 support notch filter and all-pass filter?
Hi
as title, could I load notch/all pass filter coefficient to 1452 IIR table to active related function? tested even all data is correct and it still could not work.
and how about the data bigger than 1 ?

Hello Power Pan,
This isn't enough information to know what is happening.
You have written out one coefficient of the filter, but the other four are missing.
Are you using a microcontroller or SigmaStudio to load the filters?
What is your concern about the data being bigger than 1?
Regards,
Joshua
Hello Power Pan,
I agree with Josh that we need more information. Attach your project would be a good start. You have to zip it before you attach it.
I just want to add that the standard library 2nd order filter does have an All Pass and Notch filter settings. Here is a screenshot showing it.

I download this file Multi-EQ_IIR-Coefficient_Calculator.xls, calculate the coef and fill in the iir table, it doesn't work. that's how come the question.
tested work but need to reverse the symbol of the coef.
