Medical Signal Decomposition Analysis by Means of Continuous Wavelet Transform

Abstract

This paper proposes a novel approach for medical signal decomposition analysis by using Continue Wavelet Transform (CWT) instead of Discrete Wavelet Transform (DWT) through specialized software. A respiration signal from MIT- BIH Minic Database is analyzed by this approach and by DWT, indicating that decomposing signal by CWT not only gives all the information that DWT gives, but also demonstrates the signal wavelet coefficients evolution in spectra, and decomposes signal into wavelet space by scaling spectrum instead of decomposes signal according to mathematical algorithm.
