ANALYSIS OF ERRORS OF DIGITAL MEASUREMENT SYSTEMS WITH PARALLEL CHANNELS

摘要

A computer model of a digital measurement system with parallel channels is developed. The system allows measuring the summarized error of a reconstructed signal in the presence of errors in individual channels. The influence of the errors of the static channel characteristic (zero offset and scaling) and the dynamic error arising as a result of channel synchronization errors is analyzed. Results of the analysis are presented in the time and frequency regions.
