Title: Instantaneous Frequency and Time-Frequency Distributions
Author: Boashash, B; Jones, G
Abstract: Instantaneous frequency estimation is an important problem in signal processing. It raises fundamental questions in signal representation, some of which have been addressed in this chapter. The original developments leading to the concept of 'instantaneous frequency' have been reviewed, and the relation of the IF to TFDs has been stressed. The concepts of inonocomponent and multicomponent signals have been discussed. Techniques of IF estimation have been presented and some applications of IF estimation have been described.
Description: This is an early Article that showed that Instantaneous frequency estimation is an important problem in signal processing and raises fundamental questions in signal representation, some of which have been addressed in this chapter, including developing the concepts of monocomponent and multicomponent. (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).
