Abstract:
A measurement process for measuring the attenuation of a line at a given frequency F and comprising the following steps:(a) the emission of an electric signal at one end of the electric line, said signal comprising a spectral component of amplitude A1 at the frequency F; (b) the measurement of the signal reflected by an other end of the line, at an end of the line from where the signal was emitted; (c) a determination of the amplitude A2 of the spectral component at the frequency F of the reflected signal; (d) a determination of the attenuation of the line from the ratio of the amplitude A2 to the amplitude A1; wherein the electric signal is emitted for a duration less than the outward and return time of a wave on the line, so as to preclude interference between the signal emitted and the signal reflected during the measurement.
