Abstract: A system, comprising: a processing circuitry that is configured to: receive a signal S1 and a signal S2, the signal S1 being generated by a first receiving coil in response to a first magnetic field, the signal S2 being generated by a second receiving coil in response to the first magnetic field, receive a signal S3 and a signal S4, the signal S3 being generated by a third receiving coil in response to a second magnetic field, the signal S4 being generated by a fourth receiving coil in response to the second magnetic field; calculate a first electrical angle based on signals S1 and S2; calculate a second electrical angle based on signals S3 and S4; and generate an output signal based on the first and second electrical angles.
