摘要：
An algorithm for the estimation of the parameters that characterize a linear combination of damped sinusoids is presented. The procedure is based on an interpolation scheme applied to the Discrete Fourier Transform samples. At first, a single damped exponential signal is analyzed; then the results are extended to multiple damped sinewaves. Numerical simulations show the good accuracy obtained under various measurement conditions; both the effects of spectral interference and wide-band noise are considered, proving the reliability of the proposed method in a number of engineering applications.
