Abstract :
Synthetic signals simulating uterine EHG are created in order to compare and validate autoregressive spectra, short time Fourier transform, and smoothed pseudo Wigner Ville distribution. Various criteria are computed like the global concentration and comparison between the observed frequency modulation and the true modulating signal
