I have tried out your settings on my end, did not get the errors. Filters can be designed. Please make sure you are using MATLAB 2016a and later and your filter wizard version is the latest. filter

Hi, You can see from my screenshot that I have the latest 16.1.1 version running. In your screenshot, the version number seems to have an extension. Is it the same version available at following link? https://github.com/analogdevicesinc/ad936x-filter-wizard/releases

I am using Matlab2016a.

Hi, I am using the filter wizard from 2016_R1 branch: https://github.com/analogdevicesinc/ad936x-filter-wizard/tree/2016_R1 It is possible that some of the changes in this branch are ahead of the major releases.

Thank you. I downloaded the files from the branch and am able to design the filter.
