Abstract
A signal generator comprises a signal provider and a signal processing unit. The signal provider is configured to provide a sensor signal indicating a repeatedly detected event, occurring within differing time intervals. The signal processing unit is configured to generate a transmit signal based on the sensor signal. The transmit signal comprises event information representing the temporal occurrence of the event and additional information representing additional data. The event information comprises pulses associated to detected events, wherein the pulses are temporarily separated within the transmit signal according to the differing time intervals of detected events so that each time interval of the differing time intervals comprises one pulse associated to a detected event. Further, the additional data comprises at least one frame comprising a predefined number of additional data bits. The information of the additional data bits of the at least one frame is distributed over at least two time intervals of the differing time intervals.
