Title: Digital position sensor for sensing position of a moving target

Abstract: A moving target opposite a stationary analog sensor has two sensitive elements delivering two sinusoidal output signals, of equal maximum amplitudes, centered on the same average value, in quadrature and with a period equal to one revolution of the target. A device for processing the two output signals, generates n output signals in-parallel, where n is a positive whole number greater than or equal to 2, for providing the position of a rotating component, connected to the moving target, with a resolution equal to 2.sup.n. The processing device includes a generator device, a detection device, a multiplexing device and an interpolation device.
