Results of independent metrological testing of programs for calculation of the heart rate variability parameters

7.3.Noise descriptions of the programs of calculation of spectrum of HRV

We will remind that non-linearity of amplitude-frequency characteristic is calculated as a relation of difference of maximal and minimum values of the calculated powers of spectrum in relation to the mean value of the calculated power (0% is absolute linearness)

Notes:
1. By a grey color is selected tests with the extremely low set powers which actual for the special objects of researches (look the chapter);
2 no data - the program did not execute calculations with this selection;
3.zero - in the results of test program reported about zero mistake.
4.Programs CardioSpectrum and CARDIO-10DX calculate spectrum power in integer format, therefore in area of extreme low powers (2ms2) the results of calculation of noise descriptions are substantially distorted
