Abstract

Abstract Multiplexed seismic data representing a plurality of seismic channels intensity modulates each sweep of the electron beam on a cathode-ray tube. Each successive sweep of the electron beam is photographically reproduced on a rotating drum plotter to provide a plurality of seismic traces. Timing lines are recorded at fixed time intervals along the length of the seismic traces as they are recorded on the drum plotter. A generator provides timing number signals for selected timing lines to intensity modulate the electron beam on the cathode-ray tube so that timing numbers are photographically reproduced adjacent the selected timing lines.
