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.   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.  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.
