ABSTRACT:
An electronic circuit is disclosed wherein a two-stage DC offset filter is provided and implemented serially to coincide with serially implemented seismic data gathers. A first stage corrects the offset in a multichannel system due to amplification stages common to all channels. A second stage includes a circuit for determining the DC offset unique to each channel and compensates for each channel automatically and individually.
