Abstract:
An unlocked detector for a digital delay lock loop employs an up-down counter which periodically accumulates the algebraic sum of the quantized positive and negative adjustments made at a preselected rate by the incremental phase modulator. Whenever this sum reaches a specified threshold value corresponding to a particular phase error, an unlocked indication is given. Arrangements using the same principle are disclosed for analog loops.
