1. A method of determining a data signal imposed on a phase jitter modulation (PJM) signal, the method comprising the steps of:

  • providing a first phase jitter modulated signal;

    applying a delay of less than one bit period to the first phase jitter modulated signal and obtaining a second phase jitter modulated signal;

    comparing the first and second phase jitter modulated signals;

    determining a phase difference as a result of the comparison between the first and second phase jitter modulated signals;

    generating a recovery signal based on the comparison; and

    reconstructing a data signal based on the recovery signal and an average DC value of the recovery signal.
