Adaptive seismic signal processor

Description

This patent describes an adaptive seismic signal processor with a portable seismic data acquisition unit for providing sampling rates for recording digitized seismic signals in the portable seismic data acquisition unit. It consists of: processor means with the seismic data acquisition unit for sampling digitized seismic signals at sampling rates and for passing cooperatively coupled frequency domains of the sampled digitized seismic signal so as to preclude the generation of alias frequencies, wherein pass band frequency domains are determined from a set of digital filter coefficients; programmable memory means with the seismic data acquisition unit for storing sets of filter coefficients for determining pass band frequency domains; and selector means with the seismic data acquisition unit responsive to command signals from a remote location for selecting one sampling rates and for addressing one of the sets of filter coefficients in the programmable memory means to the processor means whereby the processor means samples and passes a cooperatively coupled pass band frequency domain of the digitized seismic signal
