This package is a set MatLab scripts that implement some Teager-Kaiser (TK) energy operator and their extensions for time and frequency signal analysis. Theses scripts were written by Abdel Boudraa (Ecole Navale/Arts & Métiers ParisTech) and are distributed in the hope that they will be useful. If you have any comments or want to report bugs or to propose improvements, feel free to send me an email (boudra(at)ecole-navale(dot)fr).
