摘要：

In this paper, we present estimators of instantaneous frequency (IF) and group delay (GD) obtained from dual evolutionary spectral estimators, the evolutionary periodogram and the transitory evolutionary periodogram. We obtain the IF and the GD estimators using the first moments. We show that IF and GD may be estimated using a sample of evolutionary time and spectral correlation functions, respectively. Examples illustrating the performances of the estimators are presented. (C) 2001 Elsevier Science B.V. All rights reserved.
