Our experience has shown that both zones of exploration in covered regions.
Eigen values are computed layer. Such a situation is of great economic to study the resolution of various parameters.
If at a given receiver position the energy level is greatly different from one source than from another source, then FIELD TECHNIQUE we may have difficutty in extracting the weaker trace from the stronger trace. If we operate two sets of Figure 1 illustrates the technique we used to sources at two adjacent source positions, then the simultaneously record data from adjacent pairs of energy levels from the two sets of sources at any source points. We recorded 60 traces from each of two receiver position will not be greatly different and source point for a total of 120 traces simultaneously. We satisfactory separation of the traces is relatively easy.
This technique has been described in earlier presentations.

The device contains a appropriately shaped, the digital Alter can then fourth order delta-sigma modulator and a digital remove out-of-band quantization noise.
With an air gap of 2 mm (0.08 in);he loss in'dead' volume is about 20%. AS .his is caused by fixed machining and iUMMARY Also, if The availability of small, powerful Rare limensions are reduced the length of wire in Iarth magnets in the mid 1980's coupled with;he gap is reduced and more turns of a;he move to high channel count systems thinner wire are necessary to maintain iparked interest in the seismic industry for sensitivity at an acceptable level. With smaller, lighter geophones with the same or thinner wire however, the relative influence better specifications than the standard sized)f the insulation layer increases and the leophone.
