The detection of weak signals has made a dramatic advance with the recognition of the constructiverole that noise can play in the study of weak periodic signals. In this paper we show that the enhancement of weak signals has a wider reach, and is not confined to dynamical systems. In particular, the addition of artificial noise to a principal components analysis of a geographical problem permitted the discrimination between very weak but informative components, and the noise inherent in the data. The mechanism involved is discussed.

Abstract
The detection of weak signals has made a dramatic advance with the recognition of the constructiverole that noise can play in the study of weak periodic signals. In this paper we show that the enhancement of weak signals has a wider reach, and is not confined to dynamical systems. In particular, the addition of artificial noise to a principal components analysis of a geographical problem permitted the discrimination between very weak but informative components, and the noise inherent in the data. The mechanism involved is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
