ABSTRACT:
For use with an acoustic transmitter in an acoustic well logging tool, an improved transducer modification circuit is set forth in the preferred and illustrated embodiment. The circuit of this disclosure modifies the diameter resonant frequency of a piezoelectric transducer, thereby expanding the frequency range downward for the transmitter transducer by moving the diameter resonant frequency.
