Abstract

A lean signal processing method, a bearing monitoring unit and a wheel monitoring unit using the lean signal processing method are presented that are especially suitable for embedded systems. The invention is based on the basic inventive idea of digitally adjusting measured signals that are to be analyzed in different frequency bands to thereby enable to have a single common analogue front end and a single common digital spectrum analyzer back end. This will save analogue components and relax the need for memory in addition to a lean signal processing.
