Abstract

A method for marking a signal edge, which has been removed from at least one decimated binary signal after the decimation of an associated binary signal, within the decimated binary signal, establishes successive signal portions of the respective binary signal, in each case with a number of sampled values corresponding to a decimation factor of the decimation. It detects a signal edge removed through decimation from each signal portion if the number of signal edges determined in each signal portion of the respective binary signal is greater than one. Then, the sampled values of the respective decimated binary signal are determined through decimation of the sampled values of the associated binary signal with the decimation factor, and the removed signal edge at the sampling time of the decimated binary signal which corresponds to the signal portion of the associated binary signal with the signal edge removed through decimation is marked.
