Abstract
A system includes first precision rectifier operatively connected to receive high and low signals of a sine coil of a resolver and to output a first signaled condition and an exciter coil of the resolver. A second precision rectifier is operatively connected to receive high and low signals of a cosine coil of the resolver and to output a second signaled condition. A quadrant detection circuit operatively connected to receive high and low signals of the exciter coil of the resolver, high and low signals from the sine coil, and high and low signals from the cosine coil. The quadrant detection circuit outputs a signal indicative of quadrant position of the resolver.
