Abstract
Method of angular measurement by a resonator associated with a vibration setting device and with a vibration detector, which are linked to a processing circuit through which there travel control signals and measurement signals, the method comprising the steps of digitizing the measurement signals and of deducing an angular measurement from the measurement signals. The method comprises the steps of performing a spectral analysis of the digitized measurement signals so as to detect harmonic distortions therein and correcting at least some of the signals travelling through the processing circuit so as to attenuate the non-linearities.
