ABSTRACT:
An analog reproducer unit for a seismic exploration vessel includes a discriminator for checking the repetition rate of recorded strobe pulses to discriminate valid strobe pulses from noise. The valid strobe pulses are used to store digital samples in a digital memory. These digital samples are retrieved from a magnetic record produced in an on-bottom seismometer unit.
