Beschreibung
Zusammenfassung:	A method for detecting oscillation in a signal coupling device includes at least one oscillation detection step. The oscillation detection step includes the steps of determining an undamped signal level of a signal on a signal path of the signal coupling device in a first step, reducing a gain of the signal path in a second step, and determining a damped signal level of the signal on the signal path and a deviation between the undamped signal level and the damped signal level at least once in a third step. An oscillation is detected if at least one deviation determined in the third step of the at least one oscillation detection step is higher than or equal to a predetermined oscillation threshold value. A device for detecting oscillation in a signal coupling device and a signal coupling device are also provided.
