In the decade after the publication of the first edition of this book, advances in the field of time-frequency signal analysis and processing accumulated to an extent that called for an expanded and updated edition. This second edition contains:

over 30 new sections by leading experts in their respective fields; covering new time-frequency ( t , f ) methods, techniques, algorithms, and applications;

new tutorial sections on AM/FM decomposition of signals ( the most important;

a new chapter on Getting Started in ( t , f ) computation using the original ( t , f ) toolbox updated for this second Edition ();

a new introductory chapter (numbered to minimize numbering changes), written at a more intuitive level, making the book accessible to a wider readership reflecting the widening use of the ( t , f ) approach; and

a new chapter on ( t , f ) methods in neuroscience. This emerging field of ( t , f ) application is the subject of the new ).

Among the new sections, four relate ( t , f ) methods to time-scale methods ().

More information on the scope of new and existing chapter/sections appears in the table of contents and chapter overviews.

The ( t , f ) toolbox package (available at the Elsevier website) complements the other chapters of this book. It describes in a simple way the most important algorithms presented in the book and makes them ready for use via an easy practical graphical user interface (GUI). With the aid of ), or as a set of Matlab -compatible commands that can be accessed from the command line or called from other programs, or as source code that can be adapted for particular applications.

The ( t,f ) toolbox TFSAP is a recent upgrade to the package formerly known as TFSA, the first package in its field, which was released publicly in 1987 at the inaugural ISSPA conference in Brisbane, Australia, and frequently upgraded thereafter. It was originally purchased by several hundred universities and research institutions throughout the world, and also made available free of charge as part of evaluation agreements.

In addition to new material, this second edition also updates the text and references of existing sections, ensures more consistent use of common terminology and notations, and enriches the cross-referencing between the various parts of the book. The result is a comprehensive and connected presentation of standard and novel topics in ( t , f ) signal analysis and processing. My hope is that it achieves the best possible outcome, within the constraints of a single volume, in equipping modern researchers and engineers with the information and tools necessary to undertake any study, research, or development project in this important scientific field.

I thank several colleagues, postdocs, and research assistants who provided much needed help to complete this project. First, Dr Gavin Putland and Ms Ayat Salim assisted with LATE X editing of the sections in the book and all related tasks. In addition, several other colleagues contributed to the technical reviews of individual chapters or sections; they include: S. Ouelha, N. A. Khan, E. Sejdic, S. Touati, S. Ali, A. Assa-El-Bey, G. Azemi, J. OToole, S. Aviyente, B. Jawad, N. Stevenson, H. Hassanpour, A. Saleem, S. Dong, A. Zuri-Shaameri, M. A. Awal, A. Ouahabi and M. Alsad. In addition, all individual sections of this book were technically reviewed by at least two experts in the field, as shown in the first page of each section.

Publication of this second edition was facilitated by several grants from Qatar Foundation. In particular, the work in the contributions in was funded by the Australian Research Council and the National Health & Medical Research Council, Australia.

Time-Frequency Signal Analysis and Processing (TFSAP) is a collection of theory and algorithms used for analysis and processing of nonstationary signals, as found in a wide range of applications including telecommunications, radar, and biomedical engineering. This book brings together the main knowledge of TFSAP, from theory to applications, in a user-friendly reference suitable for both expert and nonexpert readers.

The contents of the book include:

a comprehensive tutorial introduction to TFSAP, accessible to anyone who has taken a first course in signals and systems;
