Engineering Contradiction Analysis
1Reliability
If signal coupling devices amplify signals in communication networks, then signal transmission quality is improved, but signal oscillations occur that negatively affect desired signals and time synchronization
Solution Approach 1:
The patent applies preliminary action by measuring the signal level before amplification and comparing it with a threshold value to predict potential oscillations before they occur. The control circuit proactively adjusts amplification factors based on predicted oscillation probability, preventing oscillations rather than reacting to them after they occur. This is evident in the method steps where signal level measurement and threshold comparison are performed before signal amplification to determine optimal amplification factors that prevent oscillations.
2Reliability
If existing methods are used to detect oscillations, then some oscillation detection is possible, but detection is not reliable and fast enough to effectively mitigate oscillations
Solution Approach 1:
The patent performs preliminary measurement of signal levels and pre-calculates oscillation probability by comparing measured levels with stored threshold values before oscillations fully develop. This allows the system to detect potential oscillations in advance and adjust amplification factors proactively, achieving both fast detection and high reliability by preventing oscillations before they negatively impact signal transmission.
Solution Approach 2:
The patent implements a feedback mechanism where the control circuit continuously monitors signal levels, compares them with threshold values, and adjusts amplification factors based on the comparison results. The system measures signal levels, determines oscillation probability, adjusts amplification factors accordingly, and then continues monitoring to verify the effect, creating a closed-loop feedback system that ensures reliable and timely oscillation detection and mitigation.

AI summary
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 (1) and a signal coupling device (1) are also provided.
