## Role of low-pass filtering in the process of attractor reconstruction from experimental chaotic time series

We discuss issues concerning the reconstruction of attractors from experimental chaotic time-series data using Takens's method of delays [in [ital Proceedings] [ital of] [ital the] [ital Warwick] [ital Symposium], 1981, edited by D. A. Rand and L. S. Young (Springer, New York, 1981)]. The focus of this paper is on the selection of appropriate lag-time and embedding-dimension values with an emphasis on the relationship between those parameters and data-measurement considerations. We are particularly interested in the effect that low-pass filtering has on the appearance and measured properties of reconstructed attractors. Empirical results are presented using data measured from a laboratorymore »
