Reducing the Effects of Record Truncation Discontinuities in Waveform Reconstructions

Abstract

Record truncation discontinuities (RTD's) are artifacts in recorded data caused by the difference between the values of the data at the two ends of the record. The RTD causes errors in waveform reconstructions, in particular, in digital reconstructions that use a deconvolution process. Consequently, we examine the effects of these RTD's on reconstructions of discrete-time waveforms. Four previously proposed methods for reducing the effects of the RTD on the spectra of step-like wave-forms are examined for application in deconvolution, and a comparison of their effects in deconvolution is given. An analysis of the errors is given for each case
