ABSTRACT:
This invention is concerned with systems for converting seismic waves received at various points at the surface of the earth into digital signals and the transmission of those digital signals from the geophone stations to a recording truck. Address registers located at the geophones are employed to permit periodic selective interrogation of the individual geophones. Typically, electric signals generated in the geophones, such as digital seismic signals, are time-multiplexed for return to a recorder over a common cable.
