Abstract :
The application of minimum cross-entropy (MCE) spectral analysis to successive blocks of biological time series is considered. Examples demonstrate the effectiveness of the MCE procedure for the analysis of cardiovascular ultrasound return and low-frequency electroencephalograph (EEG) signals.<>
