Time Frequency Analysis: Theory and Applications

By Leon Cohen

Featuring traditional coverage as well as new research results that, until now, have been scattered throughout the professional literature, this book brings together--in simple language--the basic ideas and methods that have been developed to study natural and man-made signals whose frequency content changes with time--e.g., speech, sonar and radar, optical images, mechanical vibrations, acoustic signals, biological/biomedical and geophysical signals. KEY TOPICS: Covers time analysis, frequency analysis, and scale analysis; time-bandwidth relations; instantaneous frequency; densities and local quantities; the short time Fourier Transform; time-frequency analysis; the Wigner representation; time-frequency representations; computation methods; the synthesis problem; spatial-spatial/frequency representations; time-scale representations; operators; general joint representations; stochastic signals; and higher order time-frequency distributions. Illustrates each concept with examples and shows how the methods have been extended to other variables, such as scale. MARKET: For engineers, acoustic scientists, medical scientists and developers, mathematicians, physicists, and mangers working in the fields of acoustics, sonar, radar, image processing, biomedical devices, communication.

Great for Maths + Discussion; Weak on Implementation

This book is written clearly and well by a leading researcher in the area of time-frequency analysis. The main weakness, and the reason I've knocked off one star, is that the book deals exclusively with continuous-time representations. If you are specifically interested in discrete-time implementation of time-frequency representations, then this book may not be for you.

Great primer for Time-Frequency

I like this book... while many books on the subject, or similar Filter Banks and/or Wavelets, seem written for the expert in the field, the treatment given here is great... the author's assumption on the power of example is valid and very important to differentiate this book from others[*]. While there is little room for confusion on a math-heavy textbook, this book gives enough math and more than a sufficient level of discussion to get the subtleties across... and then follow the math! The writing style is very fluid, yet not distracting from the objective of getting the technical substance through. It reads like a book written by someone passionate about the subject.now... a book with implementation complexity and issues would be very nice.[*] I perused through the other books that I saw at the store... so this is not a conclusive statement about the other books.

very good reference for beginners to this area

This book gives a concise and comprehensive introduction to the main approaches to TF analysis. It is an essential reference for research work in this field... Well worth the price!
