METHOD AND DEVICE FOR ASCERTAINING A USEFUL SIGNAL

摘要

A method for ascertaining a useful signal. The method includes a sampling a read-in sensor signal using a first sampling frequency in order to obtain a first sampled signal and sampling the sensor signal using a second sampling frequency in order to obtain a second sampled signal, the first and the second sampling frequency differing from one another. The method further includes a step of detecting the useful signal as signal components of the first and the second sampled signal, the signal components of the first and the second sampled signal having the same frequency within a tolerance range.

1. A method for ascertaining a useful signal, the method comprising:
sampling a read-in sensor signal using a first sampling frequency to obtain a first sampled signal and sampling the sensor signal using a second sampling frequency to obtain a second sampled signal, the first and the second sampling frequency differing from one another; and detecting the useful signal as signal components of the first and the second sampled signal, the signal components of the first and the second sampled signal having the same frequency within a tolerance range.
