Abstract

This article proposes a general methodology for evaluatin. The signal-to-noise ratio (SNR) of data acquisition systems in wireless sensors nodes. This methodology enables designers to evaluat. The SNR regardless of non-stationary sensor signals behaviour (with unknown signal shapes) or voltage supply decrease due to battery depletion. The proposed methodology provides criteria to modify signal features and data acquisition system parameters for achieving SNR values that assure numerical stability oy the algorithms implemented int. The node. Validation measurements and an application example are presented. © 2009 IEEE.
