The invention is directed to a method for encoding data of a data signal by a periodic synchronous signal having at least two signal levels in a baseband signal. To provide a possibility by which the data of the synchronous signal can be encoded and decoded again in a simple and economical manner without having to employ the expensive hardware used in known methods, it is proposed, according to the invention, that the baseband signal is generated by combining the data signal and the synchronous signal, this combining step being carried out in such a way that, depending on the signal level of the synchronous signal, the signal level of the baseband signal lies in an associated level range independent from the data signal. The invention is also directed to a corresponding method for decoding a baseband signal and corresponding circuit arrangements. The method is preferably used for encoding and decoding audio signals.
