Abstract
A method for use in a sensor includes generating a first signal by a first sensing module in response to a magnetic field associated with a rotating target, generating a base word based on the first signal, the base word including a first base bit that is generated by comparing respective components of the first signal, reversing a respective polarity of the first signal and offsetting the first signal, generating a test word based on the first signal, the test word being generated after the respective polarity of the first signal is reversed and the first signal is offset, the test word including a first test bit that is generated by comparing the respective components of the first signal, and setting a value of an error signal based on whether the test word matches the base word.
