System And Method For Reducing Noise In A Sensor System
First Claim
1. A sensor system comprising:
- an acquisition unit comprising an analog to digital converter generating a series of digital sensor signals;
a first evaluation unit receiving the series of digital sensor signals for evaluation, wherein the first evaluation unit generates output signals that correspond to a sensor event;
a second evaluation unit independent from said first evaluation unit receiving the series of digital sensor signals;
wherein at least a first and second series of digital sensor signals is processed by the second evaluation unit to generate a control signal that is configured to select a sampling frequency controlling the analog-to-digital converter, wherein the first and second series of digital sensor signals are sampled at different sampling frequencies.

Abstract
A sensor system has an acquisition unit comprising an analog to digital converter generating a series of digital sensor signals, a first evaluation unit receiving the series of digital sensor signals for evaluation, wherein the first evaluation unit generates output signals that correspond to a sensor event, and a second evaluation unit independent from said first evaluation unit receiving the series of digital sensor signals. At least a first and second series of digital sensor signals is processed by the second evaluation unit to generate a control signal that is configured to select a sampling frequency controlling the analog-to-digital converter, wherein the first and second series of digital sensor signals are sampled at different sampling frequencies.
