Signals and Their Frequency Content
In examining the physical basis for deep seismic sounding, it should be kept in mind that, as with any other seismic method, there are three basic sets of conditions to be considered: the conditions under which the waves are generated; 2) the conditions prevalent within the medium through which the waves propagate and where they are modified to provide the information of interest; and 3) the conditions under which the waves are detected, and the selection of optimum characteristics for the recording equipment in order to provide the needed separation of signals from the noise background.
