Classification: CPC G | IPC G

Claim 8:
9. A magnetic field sensor, comprising:
a sensor designed to generate on the basis of a varying magnetic field an oscillation signal that fluctuates around a mean value; and
a processing circuit designed to generate an output signal on the basis of the oscillation signal, wherein, in a high-resolution mode different than a low-resolution mode, the processing circuit is designed to generate in each case a mean value crossing pulse in the output signal when the oscillation signal attains the mean value, and to generate in each case a limit value crossing pulse in the output signal when the oscillation signal attains at least one limit value different than the mean value,
wherein a pulse width of at least either the mean value crossing pulse or the limit value crossing pulse is set to indicate that the magnetic field sensor is operating in the high-resolution mode,
wherein the processing circuit is designed to generate the limit value crossing pulses with a pulse width that differs from each pulse width used in the low-resolution mode, and
wherein the oscillation signal represents an angle that fluctuates between 0° and 360°, successive mean value crossings of the oscillation signal correspond to angles of 0° and 180°, and the at least one limit value corresponds to an angle different than 0° and 180°.
