1. A system comprising:
a resolver including a sine coil, a cosine coil, and an exciter coil;
a resolver exciter operatively connected to excite the exciter coil, and to provide high and low signals;
a processing device operatively connected to control the resolver exciter;
first precision rectifier operatively connected to receive high and low signals of the sine coil of the resolver and to output a first signaled condition;
a second precision rectifier operatively connected to receive high and low signals of the cosine coil of the resolver and to output a second signaled condition; and
a quadrant detection circuit operatively connected to receive high and low signals of the exciter coil of the resolver from the resolver exciter, wherein the quadrant detection circuit is operatively connected to receive high and low signals from the sine coil and from the cosine coil, and to output a signal indicative of quadrant position of the resolver; and
an analog to digital converter (ADC) component operatively connected to receive the first signaled condition, the second signaled condition, and the signal indicative of quadrant position of the resolver, and to output a digital signal, wherein the ADC component includes:
a first ADC operatively connected to receive the first signaled condition and to output a
first digital signal for determining quadrant position of the resolver to the processing device;
a second ADC operatively connected to receive the second signaled condition and to output a second digital signal for determining quadrant position of the resolver to the processing device; and
a third ADC operatively connected to receive the signal indicative of quadrant position of
the resolver and to output a digital signal for determining quadrant position of the resolver to the processing device.
