摘要： A method for digital triggering of a digital recording of a digitized measurement signal having a superimposed noise signal. The method includes generating from the digitized measurement signal a digital triggering signal for the digital triggering of the digital recording of the measurement signal, and performing band-limitation of the noise signal superimposed on the digitized measurement signal via a low-pass filtering before the digital triggering signal is generated. The bandwidth of the low-pass filtering is adjusted dependent upon edge steepness of the measurement signal, in order to reduce variance σt2 in jitter of the digital triggering signal.

摘要： A method for the recovery of a clock signal from a data signal, wherein the edges of the data signal and the clock signal are each presented by an ordered sequence of timing points, comprising determining missing edges in the sequence of data-signal edges, inserting new data-signal edges (Dx) into the sequence of data-signal edges to obtain a completed sequence of data-signal edges, and recovering the clock signal from the completed sequence of data-signal edges. The detection of missing edges in the sequence of data-signal edges is based on a prediction of the clock signal (FRONT CLOCK).
