Abstract

A sensing system and method for correcting an input waveform from a coded wheel. The coded wheel is configured to generate a signal that varies with rotation of the coded wheel relative to a sensor. The sensor is configured to sense the varying signal and output a corresponding input waveform. A correction module is configured to receive the input waveform and compare the input waveform to at least one stored waveform and to correct the input waveform if a defect is detected in the coded wheel in response to the comparison.
