Abstract
A system for determining an amplitude of a sinusoidal output waveform from a sensor includes a controller configured to provide a sample signal having a sample frequency that is four times a frequency of a sinusoidal excitation waveform provided to the sensor. The sensor has inductively-coupled primary and secondary windings that produce the sinusoidal output waveform from the secondary winding when the excitation waveform is provided to the primary winding. An analog-to-digital converter measures a first and second voltage of the sensor waveform separated in time by the period of the sample frequency, and the system calculates the amplitude based on the measurements of the first and second voltages.
