ESTIMATION OF PERIODIC SIGNAL PARAMETERS BY SIGNAL AND ZERO PADDING

Dušan Agrež, Damir Ilić, Janko Drnovšek
Abstract:
In paper, a frequency domain algorithm for estimation of the sine signal parameters in the case of signal sampling by averaging in the aperture time is presented. Prior to estimations in the frequency domain the sampled signal is padded with the signal average values in the aperture times and zeroes outside. We can increase padding points and with this nearing the errors to the level as with estimations of the signal without average sampling.
