Abstract:
1. A method for measuring with a maximum error E a phase (PH) of a sinusoidal signal (V) of variable period T, of angular frequency ω=2π/T, sampled with a sampling period T/r, where r is a non-necessarily integral number, in which the phase (PH) is calculated as a time at which a straight line crossing two consecutive samples located on either side of a median value of the signal reaches said median value, and including: selecting number r from a range included between a value r round(x) being an integer closest to a real number x and G being equal to 2 i G 1 , where i is a number of bits on which samples of the sampled signal are coded, and where G 1 is a real term, included between 0 and 1, of correction of an amplitude of the sampled signal.
