Abstract
Systems and methods are presented for cancelling noise from sensed magnetostriction-based strain measurements. A drive signal corresponds to a drive coil, and a sensed signal corresponds to a sensed coil. The drive signal is used to at least partially eliminate noise similar to the drive signal from the sensed signal to generate an output signal.
