Detecting faulty digital data signal sampling involves separately counting sequences with same number of identical values, evaluating distribution of identical sequences to detect faulty sampling

摘要

The method involves detecting several sequences with a different number of successive identical sample values of the data signal, separately counting the sequences with the same number of identical sample values and evaluating the distribution of the number of identical sequences. The clock signal is used for sampling and an additional measurement clock signal with a higher clock frequency is used for faulty sample detection. The method involves detecting several sequences with a number different of successive identical sample values of the digital data signal (DS), separately counting the sequences with the same number of identical sample values and evaluating the distribution of the number of identical sequences to detect the faulty sampling. The clock signal (TS) is used for sampling and an additional measurement clock signal with a higher clock frequency is used for faulty sample detection.
