Abstract
Processing circuitry comprising an analog-to-digital converter configured to perform the techniques of this disclosure. The analog-to-digital converter may obtain, based on electrical interactions with a resolver sensor, a noisy modulated digital cosine signal (NMDCS) and a noisy modulated digital sine signal (NMDSS). The processing circuitry includes a filter configured to process the NMDCS and the NMDSS to output a filtered NMDCS and a filtered NMDSS, and a rectifier configured to process the filtered NMDCS and the filtered NMDSS to output a rectified NMDCS and a rectified NMDSS. The processing circuitry includes a digital signal processor that executes a first trained machine learning model to process the rectified NMDCS and the rectified NMDSS to obtain a demodulated DCS and a demodulated DSS, and compute, based on the demodulated DCS and the demodulated DSS, an approximate angle of the rotating element.
