How to use Auto EQ filter coefficients in general 2nd order filter?

Hello Mike,

I think what you are looking for is somewhat hidden from view yet out in the open.

Drag in a general second order filter, I would use the double precision version.

Then you click on the blue square in the middle where you can select the type of filter you want.

Then you select "IIR Coefficient". Then you will see where you can enter the coefficients. If you want to cascade several filters you simply grow the cell to add more filters and do the same for those filters. The only hassle is that you have to enter these manually. There is no way to enter these from a file. The "Load" button you see will load in the coefficients into the DSP all at one time. They are not loaded as you enter them for obvious reasons.

Thanks,

Great thanks. Will try that out. What is the difference between using those 2nd order IIR filters and the Auto EQ block as the filter?

Hello Mike,

From a filter perspective there should be no difference. What I am not certain of is the difference in the code size. So if you are getting close to the MIPS limit then it is something to look into.

I think even the code size should be the same. The real difference is the GUI.

Miguel
