A method of generating a time-frequency representation of a signal that preserves phase information by receiving the signal, calculating a joint time-frequency domain of the signal, estimating instantaneous frequencies of the joint time-frequency domain, modifying each estimated instantaneous frequency, if necessary, to correspond to a frequency of the joint time-frequency domain to which it most closely compares, redistributing the elements within the joint time-frequency domain according to the estimated instantaneous frequencies as modified, computing a magnitude for each element in the joint time-frequency domain as redistributed, and plotting the results as the time-frequency representation of the signal.Method of generating time-frequency signal representation preserving phase information745775625/11/200809/06/200520081,265Nelson; Douglas J.Smith; David C.US Patent and Trademark OfficeGoogle Patent Searchpatentimages.storage.googleapis.com/US7457756B1/US07457756-20081125-D00000.pngUnique
