Abstract: A resolver to digital converter which provides digitally generated sinusoidal voltages to apply to the stator windings of the resolver. The oscillator providing the digital pulses is connected to a counter which is reset on a particular phase of one of the stator winding voltages. The output of the counter is transferred into an output register at a particular phase of the rotor voltage with the output register thereby providing a digital reading of the angular position of the rotor. Digital comparator means are provided for insuring that the stator voltages remain exactly 90.degree. out of phase, and further means are provided for insuring that the stator voltages remain at the same amplitude.
