Do Bounded Signals Have Bounded Amplitudes?,e many methods available for determining the AM and FM of a signal, some yield an unbounded AM for some magnitude-bounded signals (including the analytic signal method). The consequences of requiring a bounded AM given a bounded signal on the method used to determine the AM and FM are examined.

A Time-Recursive Algorithm for the Computation of Auto-Ambiguity Function and the Wigner Distributi used to compute the Wigner time-frequency distribution. We use the Richman-Parks-Shenoy’s definition of the discrete-time, discrete-frequency, auto-ambiguity function for finite data sequences. Block diagram implementation of the time-recursive algorithm is described, computational complexity with

Evolutionary Maximum Entropy Spectral Estimation and Heart Rate Variability Analysis,atus of the autonomic nervous system. Although most of the HRV studies assume stationarity, the statistics of HRV signals change with time due to transients caused by physiological phenomena. Therefore, the use of time-frequency analysis to estimate the time-dependent spectrum of these non-stationar

Optimal Reconstruction of Natural Images by Small Sets of Gabor Filters,optimal reconstruction are examined. At first, the search is performed on a 1-D signal which satisfies the radial spectrum of the average of natural images. Later, these results are extended and applied to a 2-D example. It is shown that the resulting parameters are better than those of some existin
