Dear Sir,

thank you for reply. Of course i take care about blank spaces between data as you wrote.

When i say invalid i mean that impulse response from filter is invalid. For example coeffs are 1, 5, 5, 5, 5, 5 1 and impuls impuls response is same like coeffs when i set 60MSPS. When i change to 1MSPS the response is invalid only one coefficient value appears. I dont want to use decim or interpolate. Just filter two channels. Of course hardware not behaving.
