Evaluation of Data Errors Introduced by Noise, Sampling Rates and Composite Waveforms

摘要

The limitations of automatic data processing of transient signals are studied. Errors resulting from noise, sampling, and forming composite records are evaluated by considering analytical waveforms. The applications of digital filtering and trend removal are also considered. Various norms of time-domain signals are computed with the resulting errors identified for certain waveforms generic to nuclear electromagnetic pulse (NEMP) test data.
