Claim One:
1. A method for filtering signals from a nonlinear dynamical system, comprising the steps of: (a) setting an initial enhanced point to a noisy point obtained from the signals; (b) estimating an intermediate enhanced point; (c ) computing a new enhanced point using the estimated point and a weighting constant; and (d) iterating the steps (b) and (c) until the computed point converges to a true enhanced point which represents a noise reduced signal to provide filtered signals, wherein the new enhanced point is computed by the equation 8 x ^ n ( i ) = x ^ n ( i - 1 ) + K 3 &af; [ x ^ n ( i, temp ) - x ^ n ( i - 1 ) ] wherein {circumflex over (x)} n (i) is the new enhanced point, {circumflex over (x)} n (i−temp) is the intermediate enhanced point for iteration i, {circumflex over (x)} n (i−1) is the enhanced point at iteration i−1, and K 3 is a weighing constant.
