AUTOMATIC METHOD AND APPARATUS FOR DIGITALLY INDICATING RESPONSE CHARACTERISTICS OF GEOPHONES OF A GEOPHYSICAL DATA ACQUISITION SYSTEM

摘要

ABSTRACT OF THE DISCLOSUREThis invention relates to an automatic method andapparatus for quick and convenient testing of one or moregeophones of a geophysical data acquisition system throughthe generation and analysis of the impulse response character-istsic of such geophones. In particular, geophone responsecharacteristics related to first and second adjacentabsolute peak amplitudes associated with the damped equationof motion of the geophone coils are detected and digitallyindicated in a surprisingly accurate manner, irrespective ofwhether or not the testing is carried out in a laboratoryor field environment.
