Abstract
The invention relates to a phase detection method. A plurality of consecutive values of a receiving signal with a known sampling frequency fare received as a reaction to a transmitting signal having a known transmitting frequency f. Two differential values are determined, each coming from two consecutive values out of three consecutive values of the receiving signal. A phase real part and a phase imaginary part of the receiving signal are determined based on a linear relation between the phase real part, the phase imaginary part and the two differential values.
