Hi,
In the manual SBAS502B, page 23, it mentions that the digital sinc filter, which will perform the noise reduction as well as sampling rate decimation, but I can't find where mention the details of decimation.
In my application, I have fmod = 128K, and output data rate is 1K SPS, so the decimation ratio is 128, the sinc filter is applied on 128K input and generate 128K output, how to convert 128k -> 1K? average 128 samples or re-sample the output of filter at 128 sample intervals? Thanks alot.
