Phase shifted periodic signals processing device for e.g. synchro, has compensation unit correcting amplitude variation of periodic signals, phase shifts of signals and variation of phase shift between signals to produce compensated signals

摘要

The device (1) has a determination unit (3) for determining a variation coefficient from an amplitude variation of real phase shifted periodic signals (A, B), and a determination unit (4) for determining controlled phase shifts of the signals. A determination unit (5) determines a variation of a phase shift between the signals. A compensation unit (6) corrects the amplitude variation, controlled phase shifts and the variation of the phase shift for producing compensated signals. A determination unit (9) determines an angular position based on the compensated signals.
