【 摘 要 】

This paper presents the results obtained using an instantaneous frequency estimation method, based upon the detection of the peaks of the spectrogram and the scalogram. A comparison is made between these two representations, showing the advantages and the disadvantages of both. Some instantaneous frequency estimation examples are presented, using as test signals nonstationary frequency modulated signals covered with zero mean gaussian noise.
