US 11,121,850 B1 · Signal analysis method and signal analysis module

Abstract

A signal analysis method is described. The signal analysis method comprises: receiving an N-ary input signal, the input signal comprising a symbol sequence; determining at least two threshold transition times of the input signal within a predetermined time period, wherein the input signal respectively crosses an amplitude threshold of several predetermined amplitude thresholds at each of the threshold transition times; determining time intervals between the threshold transition times; evaluating the time intervals based on a set of predefined conditions; and assigning the threshold transition times to at least one symbol transition based on the evaluation. Further, a signal analysis module is described.
