Abstract
A device for simplifying transmission of analog signals received from sensors to a remote station in accordance with the invention includes at least one local electronic module including in combination a modulator for oversampling each analog signal and converting each oversampled analog signal into lower resolution digital words and a transmitter for transmitting the lower resolution words as a bit stream on at least one first transmission channel; at least one synchronization element producing a clock signal allowing synchronization of each modulator with the remote station; and at least one reception module in the remote station including a receiver for receiving the transmitted lower resolution words as a bit stream and a digital filter, coupled to the receiver, for converting each received bit stream received into digital words of a higher resolution (typically 16 or 24 bit words. The invention is useful for transmission of seismic data.
