The paper concentrates on the consequences of signal de-pendent spectral transformation from nite sets of arbi-trarily distributed samples. The spectrum support func-tion that reects the true nature of the signal spectral char-acteristics is discussed. The formation of transformation functions is based on a minimum variance lter approach. The simulation results demonstrate the capabilities of sig-nal dependent transformation for the analysis of stationary and non-stationary signals. The proposed method is par-ticularly applicable to cases where the signal is sampled non-uniformly with a density less than the Nyquist rate. 1
