ABSTRACT:
In a method and device for reconstructing and controlling the phase position of a sample clock relative to an analog signal to be sampled, the analog signal is sampled at a plurality of different instants in time during a time interval and a plurality of time gradients at the same or different instants in time are determined. The original analog signal is reconstructed, at least in segments, based on the sampled values and determined time gradients. The reconstructed signal curve is utilized to determine the phase position of the sampling clock relative to the analog signal. This phase position is provided to a control loop which readjusts the phase position of the sampling clock accordingly.
