ABSTRACT:
Multiplexed seismic data representing a plurality of seismic channels intensity modulates each sweep of the electron beam of a cathode-ray tube. Each successive sweep of the electron beam is photographically reproduced on a rotating drum plotter to provide a seismic record section. The sweep signal for controlling the electron beam is automatically gain controlled so that the number of seismic traces per inch remains constant.
