Abstract: Time-frequency analysis techniques are effective in detecting local signal structure and have been applied successfully in a wide range of fields. Different time-frequency analysis transforms yield different time-frequency spectra. However, visualizing a four-dimensional complex-valued time-frequency spectrum is not a trivial task. Here, we propose a new way to visualize a complex-valued time-frequency spectrum in one graph. We show that the proposed visualization tool may facilitate better understanding of local signal behavior.
