Unconventional Tocographic Signal Analysis
MetadataShow full item record
Spectrum estimation belongs to the most frequent problems solved by the digital stochastic signal processing. The application of the unconventional method of spectrum estimation based on maximum entropy approach introduced by J. P. Burg is presented. Drawbacks of classical spectrum estimation methods involving interpretation difficulties are avoided. Basic principles and underlying conceptions yielding the same results as autoregressive modelling and reasonableness of its application are discussed. Stochastic biosignal reflecting fetus movements obtained by the tocography is analyzed by the maximum entropy method and compared to the conventional method of Fourier analysis.
