Digital seismic prospection station

摘要

In addition to components of known stations the station includes: a coded information recording impulse formation block with input connected to the output of the analogue digital converter and with output connected to the coded information recorder heads in the magnetic recorder. A coded information recording pattern control circuit has its input connected to the output of the reproduction amplifiers to control the analogue-digital converter and the multiplexer. It also switches the recording impulse formation circuit from the first excitation recording pattern to the consecutive excitations recording pattern. A read coded information memory is connected to the reproduction amplifiers output and an adder of the coded information from the sum of the preceding excitations to that from the current excitation is connected to the memory output and to the second output from the analogue-digital converter. The adder output is connected to the third input of the recording impulse formation circuit.
