Digital field compositing system

摘要

This invention relates to the processing of electrical signals and to an improved method and apparatus for combining or compositing in the field electric signals derived from a seismic exploration system, thereby obtaining a reduction in the cost of processing digital tapes by office computers as well as providing to the geologist in the field on-the-spot information useful to better guide the progress of the exploration crews. Each sample of raw data may be selectively eliminated from or added to the results of the compositing process.
