Abstract
The ability of an adaptive line enhancer (ALE) driven by the least-mean-square (LMS) algorithm to track the frequency of a chirping signal in broadband noise is discussed. The dynamic behavior of the weights is described, and a weight tracking error bound is derived in terms of the chirp rate. Frequency tracking and weight behavior are illustrated by means of examples
