Zusammenfassung:A seismometer weighting apparatus is described which uses solid-state operational amplifiers for conveniently applying weighting coefficients to individual seismometer signals which are then combined to form noise-rejecting arrays. This apparatus produces improved noise attenuation while retaining use of uniform field seismometers and equal spacing of these seismometers to expedite operations.
