ABSTRACT:
The apparatus of the present invention includes a group of at least three seismic detectors. Each seismic detector detects vibrations and provides a seismic signal in accordance with the sensed vibration. A multiplexer multiplexes the seismic signals to provide a multiplexed signal. The multiplexed signal is amplified and converted to digital signals. A memory stores the digital signals according to the detector of origin so that the stored digital signals for a detector are in effect a sample of the seismic signals from the detector. A microprocessor connected to the memory means derives a statistical reference from the stored samples. Samples that are outlying with respect to the statistical reference are discarded. The remaining samples are then combined in a predetermined manner to provide an enhanced seismic signal from the group of detectors.
