Claim 9:
10. The system according to claim 8, wherein the monitoring system extracts the main features of the pre-processed signals to be used as the extracted predictor variables, the extracted predictor variables being signal spectral variables in the frequency domain by:
truncating the background corrected vector Vb length to a floor operator LT of maximum power of 2 of the length of the background corrected vector Vb to obtain a truncated background corrected vector;
applying a Fast Fourier transform to the truncated background corrected vector using a Discrete Fast Fourier method;
obtaining the spectral power P of the background corrected vector Vb based on the result of applying the Fast Fourier transform to the truncated background corrected vector; and
truncating the obtained spectral power P to obtain the extracted predictor variables as signal spectral variables in a frequency domain vector VFREQUENCY is obtained.
