ABSTRACT:
A local buffer circuit for use with a magnetostrictive transducer is disclosed wherein the magnetostrictive transducer includes a pickup coil and the local buffer circuit includes two diodes in parallel with the pickup coil to clip or short the energy produced in the pickup coil generated by an interrogation pulse, and also includes a common emitter amplifier to reduce the electrical impedance of the pickup coil, also in parallel with the pickup coil.
