System and method for reducing noise in a sensor system

摘要

The sensor system includes an acquisition unit including an analog-to-digital converter for generating digital sensor signals of one series; A first evaluation unit for receiving digital sensor signals of the series for evaluation, wherein the first evaluation unit generates output signals corresponding to sensor events; And a second evaluation unit independent of the first evaluation unit for receiving the digital sensor signals of the series. At least first and second series of digital sensor signals are processed by the second evaluation unit to generate a control signal configured to select a sampling frequency to control the analog to digital converter, Are sampled at different sampling frequencies.
