| 摘要 |
The invention relates to a detector circuit (4) for a wake-up signal comprising a comparator circuit that is connected to an input circuit (2), an output circuit (5) being connected to the comparator circuit. Said comparator circuit comprises a window comparator (11) for frequency detection within a predetermined bandwidth, in addition to an error detection rejecter circuit (12), which is connected to the comparator circuit and only activates the output circuit (5) if there have been several valid frequency detections. |
