    FIR filter offset error - this makes FIR useless

    robert.seczkowski

      Does anyone know why FIR filter introduce fixed offset error to the input variables?

         

      Does anyone know why FIR filter  rolls off output results instead of saturate?

         

      (i.e. value withing 5 samples go down to 0 and then to 0xFFFF and again to zero).

         

      I'm not able to detect, that it's related to input variable roll-off

         

      regards
