Abstract :
We discuss the use of the covariance method for the analysis of transients, in particular to determine the number and time constants of decaying exponentials. We propose a new technique, involving the repeated use of the covariance method with many different orders, all larger than the the actual number of terms in the transient, and a comparison the results as a good means for the estimation of the true values of the parameters of interest.
