Abstract
A signal analysis method for recovering a clock signal from an input signal is described. The input signal comprises a symbol sequence, wherein each symbol has one of N different amplitude values, and wherein N is an integer bigger than 1. The signal analysis method comprises the following steps: The input signal is received. Transition times of the input signal are determined, wherein the input signal respectively crosses one of several predetermined amplitude thresholds at the transition times. The transition times are transformed into one reference symbol period, thereby obtaining transformed transition times. The clock signal is determined based on the transformed transition times. Further, a signal analysis module for recovering a clock signal from an input signal is described.
