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. Featuring traditional coverage as well as new research results that, until now, have been scattered throughout the professional literature, this book brings togetherin simple languagethe basic ideas and methods that have been developed to study natural and man-made signals whose frequency content changes with timee.g., speech, sonar and radar, optical images, mechanical vibrations, acoustic signals, biological/biomedical and geophysical signals. 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.Cohen, Leon is the author of 'Time-Frequency Analysis', published 1995 under ISBN 9780135945322 and ISBN 0135945321.
