Abstract
A seismic data acquisition device and a seismic data acquisition method are disclosed. The seismic data acquisition device includes an anti-aliasing filter, a first conversion circuit, a second conversion circuit, and a controller. The anti-aliasing filter has an input configured to receive seismic data, which is generally an analog signal. The anti-aliasing filter has an output connected to an input of the first conversion circuit and an input of the second conversion circuit, respectively. The first conversion circuit has an output connected to a first input of the controller. The second conversion circuit has an output connected to a second input of the controller. The seismic data acquisition device and method enable wide dynamic seismic data acquisition with high resolution over the full amplitude range of the (seismic data) input signal.
