Abstract
An apparatus for calculating an angular speed of a rotary component includes a processor circuitry configured to: receive an in-phase signal and a quadrature signal from a sensor arrangement, each signal relating to a position of the rotary component; arithmetically sum the in-phase signal and the quadrature signal generated by the sensor arrangement to produce a combined time-domain signal; and calculate an angular speed of the rotary component based on the combined time-domain signal. Methods of calculating an angular speed of a rotary component are also provided.
