Abstract: A device that determines gradients of a signal compares the change in a signal level between two instants with reference values, and determines a measure for the signal gradient as a function of the comparison. The device functions to effect signal reconstruction, where, for example, the phase of the signal processing clock relative to the gradient measurement clock can be adjusted, or a measure for the signal values between multiple sampling points can be determined. A method for controlling signal curves based on gradient values determines a measure for the gradient curve or the curvature of the signal from the immediate time sequence of multiple gradients. Based on a sequential evaluation of these measures, it is possible to determine the direction of the phase drift of the signal and, for example, to utilize this for synchronization or phase control.

Abstract: A video signal sampling system comprises an analog-to-digital converter that samples an analog video signal under the control of a sampling clock signal to provide a digital video signal. A processor processes the digital video signal by computing at least two derivatives of the digital video signal in order to provide a phase correction signal value. A delay locked loop receives the phase correction signal value and a clock signal, and adjusts the phase of the clock signal based upon the phase correction signal value to provide the sampling clock signal.

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.
