Abstract
In a method of detecting false-locking the trains of clock signals corresponding to the two phase offset initially modulated trains of signals, the phase offset between said trains of clock signals is monitored, and false-locking is detected when the phase offset changes signal. Also, a method of demodulation implements this method of detecting false-locking. Also, a device for implementing the method of detecting false-locking contains a flip-flop in series with a monostable.
