Abstract / Hauptanspruch
The invention relates to a sensor for measuring a periodic signal comprising several harmonics wherein the first harmonic has a λ spatial period, said sensor comprising an electrical circuit of G resistive groups arranged in a current loop circuit and having a geometrical barycentre spaced by λ/G + kλ (k being an integer) from each other, each of said groups comprising at least one set of p resistive elements (1) connected in series and having a geometrical barycentre spaced by λ/pn + iλ (i being an integer) from each other, n being different from G, in order to filter at least harmonics n [2n] of the signal, said sensor comprising determination means adapted for determining at least one output which is representative of the signal, said output comprising a combination of at least some voltages V G across the G resistive groups.
