  3. Abstract:
  4. In this paper, a new method for modal parameter estimation using time-frequency representations is presented. Smoothed Pseudo Wigner-Ville representation which is a member of the Cohen's class distributions is used that reduces cross-terms in time-frequency plane dramatically and holds resolution as well. The method was applied to systems with high damping, and the results were superior to other conventional methods. © (2006) by the Katholieke Universiteit Leuven Department of Mechanical Engineering All rights reserved
