A method and a device are described for detecting at least a portion of a measuring gas component containing bound oxygen in a gas mixture, in particular in an exhaust gas of an internal combustion engine, in a measuring gas chamber by detecting a portion of oxygen that is generated by a reduction of the measuring gas component containing the bound oxygen, in the presence of molecular oxygen, in the device, which includes at least one first pump cell, one reference cell, and one second pump cell. The method includes the following steps: a) generating a first pump current in the first pump cell in such a way that transport of a first portion of oxygen ions takes place between the measuring gas chamber and the surroundings of the device; b) applying a reference pump current to the reference cell in such a way that a second portion of the oxygen ions is transported into a reference gas chamber; c) decomposing the measuring gas component containing the bound oxygen by catalysis at an electrode of the second pump cell, as the result of which additional molecular oxygen is generated from the measuring gas component; d) applying a second pump current to the second pump cell in such a way that a portion of further oxygen ions that are formed from the additional molecular oxygen is transported into the reference gas chamber; and e) holding a sum of currents, formed from the reference pump current and from the second pump current, constant.

A sensor module includes a sensor element set up to output a sensor signal, an A/D converter connected to the sensor element, a signal transmission unit connected to the A/D converter and set up for the transmission of a sensor signal converted by the A/D converter, and a supply signal tap at which an unconverted supply signal that represents a supply voltage or a supply current of the sensor module is present. An input of the A/D converter is connected to the supply signal tap. The unconverted supply signal that represents a supply voltage or a supply current of the sensor module is converted into a converted supply signal by the A/D converter that converts the sensor signal.

A control unit is described that has at least one communications interface for the exchange of data with at least one peripheral unit, the communications interface being configured for transmitting synchronization signals to the peripheral unit in a first, synchronous operating mode. The communications interface is configured to change a time interval between two successive synchronization signals.

A method for processing signals transmitted via a connection and received by a digital interface, where individual data frames are transmitted by the signals as a sequence of modulated symbols, and where the received signals are corrected by an equalizer; the equalizer sampling the received signals, and an adaptation of the equalizer only taking place in particular time intervals in a manner controlled by a protocol.
