Аннотация: This article discusses the development of specialized receiving equipment for passive and active methods for the search for hydrocarbon and solid minerals. An option is given for solving the registration of seismic / electric fields using instrumental amplifiers and a 24-bit ADC, since such a solution will minimize distortions introduced in the amplification channels, and match the input impedances, which is most important when registering an electromagnetic field with the use of a grounded electric dipole. It is proposed to build the digital part using a 24-bit sigma-delta ADC and a microcontroller built on the basis of the ARM architecture. 50 Hz industrial interference cancellation is solved using a specialized filter on switched capacitors. Such a solution will allow recording signals with amplitudes of the order of 1 μV. © 2020 IEEE.
