ABSTRACT:
A circuit is disclosed for use in an acoustic logging tool incorporating a transmitter sending an acoustic pulse which is received by acoustic receivers. In the preferred and illustrated embodiment hereof, an automatic gain control (AGC) circuit controls the receiver amplification to enable the output range to be limited for input to a digital graphic recorder, typically having a limited number of output signal levels, coordinating with data processing equipment. The AGC times the peak operation to thereby limit the dynamic range.
