Abstract: A method and a corresponding decoder for decoding a Manchester encoded binary data signal includes receiving the Manchester encoded binary data signal having a first sequence of central bit transitions and a second sequence of initial bit transitions. A local clock signal is generated, and the central bit transitions of the Manchester encoded binary data signal are determined. Determination of the central bit transitions includes measuring the time interval elapsing between a pair adjacent central bit transitions, expressed as a number N of cycles of the local clock signal, and selecting each successive central bit transition based upon the time interval N measured between the pair of central bit transitions which immediately precede the successive central bit transition.
