Abstract: Illustrative embodiments of systems and methods for enhanced vibration and electrical noise performance in magnetostrictive transmitters are disclosed. In one embodiment, a signal conditioning circuit may comprise an instrumentation amplifier configured to receive and amplify an analog measurement signal, an active high pass filter configured to reduce noise in a signal output by the instrumentation amplifier, a variable gain amplifier stage configured to further amplify a signal output by the active high pass filter, a distance detection module configured to process a signal output by the variable gain amplifier stage to determine a distance measurement associated with the analog measurement signal received by the instrumentation amplifier, and a programmable control circuit configured to control a gain level of the variable gain amplifier stage and to receive data concerning the signal output by the variable gain amplifier stage, including the distance measurement, from the distance detection module.
