N2 - A method of spectral calculation based on the ensemble average technique, which is a natural expansion of the Burg's maximum entropy method, is proposed. This method is applied to a set of numerical simulation data which simulates turbulent velocity fluctuations data measured in the canine aorta with a hot film anemometer. Autoregressive order of the spectral calculation is chosen by the minimum AIC (Akaike's Information Criterion) method. It is shown that the proposed method has a very good performance in the short time quasi steady spectral analysis of the turbulence in the aorta. (from English abstract)
