Abstract
At least two methods of reconstituting the original form of a time/amplitude trace, such as seismic data, are disclosed wherein the seismic data has been rectified by a scanner to produce a signal representative of a hardcopy display of the trace. One of the methods comprises selecting a time window of a certain duration, obtaining a measurement of the predominant period within the selected positive components of the signal, and filtering the signal with a bandpass filter having a range of about F/2 to about 3F/2, where F equals the reciprocal of the predominant period of the signal.
