<p>PURPOSE:To obtain a data identifier with simple constitution by identifying a data through the combination of a phase of an identification point, a phase of a recovered clock, the most significant bit of a phase error and segmentation information. CONSTITUTION:The device consists of an analog digital converter 50, an identifying point detector 51, a phase calculator 52, a phase synchronizing circuit 58 and a data discriminator 59. Then the clock of a PCM signal subject to analog digital conversion is recovered and the data is identified by the combination of the phase of identifying point, phase of a recovered clock, a phase error and a segmentation number signal. Thus, the data identifying device is obtained with simple constitution.</p> |
