False-lock detection and coherent demodulation of digital date.

摘要

In the method of detecting false latchings, the clock trains corresponding to two initially offset modulated signal trains are recovered, the offset between the said clock trains is noted and a false latching is detected when this offset changes sign. The method of demodulation implements this method of detecting false latchings. The device for implementing the method of detecting false latchings comprises a flip-flop (12) in series with a monostable (13). <IMAGE>
