An introduction to time-frequency signal analysis
Provides an introduction to the field of time-frequency analysis by reviewing four important and popular used time-frequency analysis methods with focus on the principles and implementation. The basic idea of time-frequency analysis is to understand and describe situations where the frequency content of a signal is changing in time. Although time-frequency analysis had its origin almost 50 years ago, significant advances have occurred in the past 15 years or so. Recently, the time-frequency representation has received considerable attention as a powerful tool for analysing a variety of signals and systems.
