Abstract
A magnetostrictive linear position transducer of the type having an acoustic magnetostrictive waveguide for propagating acoustic pulses generated by the interaction of a permanent magnetic field with a periodic excitation magnetic field. The mode convertor for converting acoustic pulse into an electrical signal indicative of the passage of an acoustic pulse propagated pat the mode convertor location along the waveguide includes a passband type filter for improving the detectability of the acoustic signal.
