Abstract
This paper considers methods for the analysis of non-stationary processes – the wavelet transform and the Hilbert-Huang transform. A comparative analysis of the results of time-frequency analysis of the human pulse signal using these methods has been carried out. The wavelet image and the Hilbert spectrum of instantaneous frequencies are presented here. It is shown that the obtained results are in good agreement with each other. The Hilbert-Huang transform allows for a more accurate assessment of the dynamics of changes in the spectral components of the signal over time.
