Device for measuring a modulation signal modulated on a power signal on a non-polarized bus designed to be connected to a rectifier circuit of a bus device, comprising a differentiator for differentiating the power signal modulated with the modulation signal, which differentiator is arranged to detect a flank of the modulation signal; a bias voltage circuit for providing a bias voltage; a comparator coupled to the differentiator and the bias voltage circuit in such a way that an output signal is obtained which is representative for the modulation signal and which is suitable for further processing. |
