Abstract
A smoothing, which has the effect of a Gaussian filter, has been performed on noisy chaotic digitized laser signals. It is shown that this smoothing can unravel distinguishing features of chaos in the phase space plots and first return maps and hence is useful in unambiguously differentiating chaos from noise. The calculation of the correlation dimensions reveal that the dynamics of the signals are not drastically affected by the smoothing. The type of smoothing discussed in this paper is useful in analyzing chaotic data sets corrupted by additive noise from the signal detection process.
