Abstract: Method and decoder for decoding a Manchester encoded binary data signal (RX_DATA). The decoding method comprises the following steps:

receiving the binary data signal (RX_DATA) comprising a first sequence of bit central transitions (40) and a second sequence of bit initial transitions (42),
generating a local clock signal (CK), and
determining the central transitions (40) of said encoded binary data signal (RX_DATA),
   and is characterized in that the central transition (40) determination step comprises the following steps:

measuring, by means of the local clock signal (CK), the time interval elapsing between a pair adjacent central transitions (40), expressed as a number N of cycles of the local clock signal (CK),
selecting each successive central transition (40) on the basis of the time interval N measured between the pair of central transitions (40) which immediately precede said successive central transition (40).
