METHOD FOR CORRECTING AN OSCILLATOR FREQUENCY

A method for correcting an oscillator frequency of in particular a digital transmitter/receiver interface for transmitting measurement signals of a sensor to a control unit. The method includes outputting of a first reference frequency signal by the sensor, the first reference frequency signal and c...

Beschreibung
Zusammenfassung:	A method for correcting an oscillator frequency of in particular a digital transmitter/receiver interface for transmitting measurement signals of a sensor to a control unit. The method includes outputting of a first reference frequency signal by the sensor, the first reference frequency signal and comparing it with a second reference frequency signal by the control unit, calculating a correction factor on the basis of the first and second reference frequency signals, and correcting the frequency signals representing actual measured quantities subsequently sent by the sensor and received by the control unit based on the calculated correction factor to obtain corrected frequency signals.
