98 Part CNote:For the first points, value of index “i” will be less than or equal to zero; it means that forf .summation you have only values beginning with x 1For the first point for summation you have: f x 1 , f x 0, f x 1 .f x 1 and f x 0 - don’t exist, so you have only f x 1 .For the second point for summation you have: f x 0, f x 1 , x 2f - doesn’t exist, so you have only f + f .x 0Via samples, root mean squareFxjjfij s1xs 1i2Where:i - index for source values (***the real range is 1..j);j - index for destination values (1..n);n - number of samples;x , x - values of points at horizontal axis;fiFx ix jj- values of points of a curve;- integrated values of points of a curve;s – number of samples to average across.Via samples, root mean square, remove baselinex 1x 2f .Fxjjijs1 fxis 1jfmjs1kxm2Where:i and m- indexes for source values (***the real range is 1..j);j - index for destination values (1..n);n - number of samples;x , x - values of points at horizontal axis;fiFx ix jj- values of points of a curve;- integrate values of points of a curve;s – number of samples to average across.k – coefficient :For the first few points that have index j < s k=j, for the other points with j > =sk=sVisit the online support center at www.biopac.com
