| Popis: |
spectrogram obtained by complex (AR) modelling was investigated using -the Yule-Walker equations. The spectral envelope area (SEA) was used to evaluate the effect of window duration on AR spectrogram, and a statistical analysis indicated that the SEA was not sensitive to window duration. The white-noise like behavior of the modelling error indicates that the Doppler blood flow signal can be modelled adequately as a complex AR process. |
