Figure 5From: Using information theoretic distance measures for solving the permutation problem of blind source separation of speech signalsComparison of the assumed pdfs and the histograms of the speech signal at different frequencies. Histograms of the amplitudes of a clean speech signal (white bar) and the Rayleigh probability distribution functions (black line) that were calculated for the clean speech data at (a) 1,000 Hz, (b) 2,000 Hz, (c) 3,000 Hz and (d) 4,000 HzBack to article page
