Abstract
A flux-gate magnetometer having a drive signal for reducing the effects of electromagnetic interference (EMI) is provided. The drive signal has a characteristic that varies over time. For example, the drive signal may include a duty cycle that varies over time, the frequency of the drive signal may be varied over time, or the phase shift of the drive signal may vary over time.
