Abstract:
The frequency content of many biomedical signal s can change rapidly with time. Conventional Fourier spectral analysis techniques are insufficient for analyzing the time-varying spectral content of these signals. By mapping a one-dimensional function of time(or frequency), the time-frequency representation can localize the signal energy in both the time and frequ ency directions. It has been shown that many biomedical signal problems may benefit from time-frequency analysis. The basic method of time-frequency analys is and its application in biomedical signals processing are introduced.
