Förfarande för bestämning av tidsläget för en periodiskt återkommande signal

摘要

The present invention relates to a method for determining the position of a periodic signal with a signal strength where the determination of the position takes place in a number of steps. First, values (32) that are related to the periodic signal are accumulated over a number of periods in a buffer. Thereafter, an area (34) with the lowest accumulated values in the buffer is detected for determination of a zero position (35). A mean position (36) is determined with respect to the zero position (35) and thereafter the position of the periodic signal is calculated with the help of this determined mean position (36).
