| | Abstract | | Microsecond sampling is required in order to pick the time difference of around 1 microsecond in the travel time tomography for the model experiments or the excavation disturbed zone survey. Among the commercial recorders, there are various constraints such as narrow dynamic range or number of usable channels. Therefore, we present about development of the multi-channel seismic recording system with the characteristics of wide dynamic ranges and high speed samplings. |
