ABSTRACT:
Described is a digital phase lock device comprising a feedback loop having a plurality of delay elements and a selector. The delay elements delay a sampling signal into signals having different time delay values relative to the sampling signal. These delay signals are compared with a periodic target signal whereby one of them is selected as the next sampling signal. As a result, the sampling signal tracks the periodic signal.
