- Abstract:
- In the paper the analytical evaluation of theuncertainty on signal parameter estimation in frequency domain is dealt with. Two different and widely diffused algorithms able to compensate the spectral leakage effects due to asynchronous sampling are considered. The combined uncertainties on the final results (tones frequency, amplitude, and phase) due to the propagation of the uncertainty on the input samples are analytically evaluated. Simulation tests are then carried out in order to validate the obtained formulas.
