Reducing the effects of record truncation discontinuities in waveform reconstructions

Record truncation discontinuities (RTDs) 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. The effects of the RTDs on reconstructions of discrete-time waveforms are examined. Four previously proposed methods for reducing the effects of RTD on the spectra of step-like waveforms 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.<
