Abstract
A signal encoder for encoding a wheel speed sensor signal includes an input interface. The input interface is configured to receive a wheel speed sensor signal providing speed information and additional information. Furthermore, the signal encoder includes a signal processing circuit. The signal processing circuit is configured to generate a first and a second speed pulse. A time interval between the first and the second speed pulse corresponds to the speed information. Additionally, the signal processing circuit is configured to generate a data pulse between the first and the second speed pulse based on the additional information. The generation of the data pulse is in in accordance with a modulation scheme having a modulation order of at least three. Furthermore, the signal encoder includes an output interface. The output interface is configured to sequentially output the first speed pulse, the data pulse, and the second speed pulse.
