    Cross-terms in time-frequency representations of signal's energy: (a + b)^2 = a^2 + b^2 + 2ab. Wigner-Ville transform of a signal composed of two sine waves with compact and separated support (below). The middle structure (labelled "2ab"), appearing in the time coordinates where the signal is flat, is a cross-term.
