Method for evaluating an analog signal by evaluating digital data corresponding to the analog signal to determine zero crossings of the analog signal |
摘要 |
A method for evaluating an analog signal of an inductive sensor that carries data on a rotational motion includes directly connecting the inductive sensor to an A-D converter via resistors, and reading in the analog signal by the A-D converter to emit digital data. The digital data is evaluated to determine zero crossings of the analog signal. |

1. A method for evaluating an analog signal of an inductive sensor, which carries data on a rotational motion, comprising:
directly connecting the inductive sensor to an A-D converter via resistors; reading in the analog signal by the A-D converter to emit digital data corresponding to the analog signal; and evaluating the digital data to determine zero crossings of the analog signal; wherein the resistors limit a current so that the A-D converter is not damaged by overloading. |
