SIGNAL PROCESSING METHOD AND DEVICE

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 anda 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. 提供精简的信号处理方法、使用精简的信号处理方法的轴承监视单元和车轮监视单元，其尤其适于嵌入式系统。本发明基于这样的基本发明构思：数字地调节在不同频带中的待分析的测量信号，从而能够具有单个公共模拟前端和单个公共数字频谱分析后端。除了精简的信号处理之外，这还将节省模拟组件并缓解对存储的需求。
