Claim 15:
16. A method for determining a transfer function of an angle sensor, wherein the method comprises:
generating, by the angle sensor, a sequence of angle output signals during an exposure to a rotating magnetic field;
receiving the sequence of angle output signals of the angle sensor during at least one time interval during which the angle sensor is exposed to the rotating magnetic field;
determining the transfer function of the angle sensor based on the sequence of angle output signals;
configuring the angle sensor based on the transfer function such that an angle output signal generated by the angle sensor is representative of an actual angle value;
storing one or more correction values in a look-up table; and
updating the one or more correction values in the look-up table with one or more updated correction values based on the sequence of angle output signals;
wherein determining the transfer function includes calibrating the transfer function based on the one or more updated correction values, and
wherein the one or more updated correction values are used to at least one of correct irregularities of the transfer function or to linearize the transfer function.
