Abstract
In some examples, a method includes applying a bias voltage to a resolver system. The method also includes receiving a sensed signal, the sensed signal varying in value based on a position of a rotary element. The method also includes attenuating the sensed signal to form an attenuated signal. The method also includes performing fault detection on the attenuated signal to detect faults in the resolver system. The method also includes processing the attenuated signal to determine the position of the rotary element.
