Abstract: A method for measuring with a maximum error E the phase of a substantially sinusoidal signal, of angular frequency ω=2π/T, sampled with a sampling period T/r, in which the phase is calculated as the time at which a straight line crossing two consecutive samples located on either side of a median value of the signal reaches said value, including the step of selecting number r from a range included between a value r0 and a value equal to from two to three times value r0, such that: E ≥ max t ∈ [ - T r0 , 0 ] [ t - T r0 · round ( G · sin ω t ) round ( sin [ G · ω · t + 2 π r0 ] ) - round ( G · sin ω t ) ] round(x) being the integer closest to a real number x and G being equal to 2iG1, where i is the number of bits on which are coded the samples and where G1 is a term of correction of the amplitude of the sampled signal.
