ABSTRACT:
The apparatus provides a means for time-varying the signal sample rate and the subsurface coverage during a single seismic reflection recording cycle. A number of seismic sensor arrays are connected to a multichannel seismic recording apparatus through a data-signal transmission means such as a multiconductor cable or a telemetric link. Each seismic sensor array is, of course, connected to a corresponding input channel, including a preamplifier, in the multichannel recording apparatus. Included in the recording apparatus is a set of addressable multiplexer switches. The multiplexer switches (or for simplicity, simply multiplexers) are divided into at least two groups. Separate sets of anti-aliasing filters, each set having a different pass band, are connected to the input terminals of the respective subgroups of multiplexers. One half of the input channels are connected to both sets of filters; all of the input channels are connected to one set of filters and multiplexers.
