DESCRIPTION

Seismic data recorded in digital form by each channel of the recording instrument are represented by a time series. Processing algorithms are designed for and applied to either single channel time series, individually, or multichannel time series. By referring to the field data examples, we examine characteristics of the seismic signal primary reflections from layer boundaries and random and coherent noise such as multiple reflections, reverberations, linear noise associated with guided waves and point scatterers.
