Time-Frequency Analysis of Clinical Percussion Signals Using Matrix Pencil Method
Time-frequency representations of the ideal, noise-free “resonant” (left) and “tympanic” (right) percussion signals shown in Figure 3. The “resonant” signal is a sum of four EDS; the “tympanic” signal is a sum of three EDS. (a) WVD; (b) CWD (); (c) STFT (spectrograms) taken with 1400-point Gaussian window; (d) MPM TFR (amplitudes of the original EDS comprising both signals).
