Title: Discrete Time-Frequency Distributions
Author: Boashash, B; Putland, G.R.
Abstract: Ideal sampling of window or kernel functions leads to straightforward definitions of discrete-time forms of the WVD, the windowed WVD and other quadratic TFDs. Use of the analytic signal minimizes the required sampling rate. Further theoretical details may be found in [3–5]. Some practical computational issues will be examined in Article 6.5.
Description: This Article shows that Ideal sampling of window or kernel functions leads to straightforward definitions of discrete-time forms of the WVD, the windowed WVD and other quadratic TFDs. Use of the analytic signal minimizes the required sampling rate. (Additional details can be found in the comprehensive book on Time-Frequency Signal Analysis and Processing (see http://www.elsevier.com/locate/isbn/0080443354). In addition, the most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia, and then continuously updated).
