Abstract
A Sin-Cos sensor arrangement comprises a Sin-Cos sensor operably coupled to signal processing logic via a hardware interface. The hardware interface is arranged to provide the signal processing logic with analog sine and cosine waveforms indicative of fine position data and binary counterparts of the analog sine and cosine waveforms (Phase_A and Phase_B) indicative of rough position data. The signal processing logic is arranged to determine a position and speed of the Sin-Cos sensor by compensating for inaccuracies between analog sine and cosine waveforms and their binary counterparts. In this manner, a fully software-based solution provides a fast, efficient and high accuracy position and speed estimation based on the processing of the analog sine and cosine signals and the digital representation thereof of the Sin-Cos sensor.
