Method for operating a sensor system and sensor system
First Claim
1. A method for operating a sensor system having a sensor, an analog-to-digital converter, and a digital signal-processing device, the method comprising:
- transmitting an analog signal from the sensor to the analog-to-digital converter;
converting the analog signal to a digital signal using the analog-to-digital converter with a sampling frequency;
transmitting the digital signal to the digital signal-processing device;
further transmitting the analog signal to a clock generator; and
controlling the sampling frequency of the analog-to-digital converter with the clock generator as a function of the analog signal.

Abstract
A method is provided for operating a sensor system having a sensor, an analog-to-digital converter and a digital signal-processing device, an analog signal from the sensor being transmitted to the analog-to-digital converter, the analog signal being converted to a digital signal by the analog-to-digital converter with a sampling frequency, the digital signal being transmitted to the digital signal-processing device, and the analog signal further being transmitted to a clock generator, the sampling frequency of the analog-to-digital converter being controlled by the clock generator as a function of the analog signal.
