Високопродуктивна система цифрового реєстрування аналогових сигналів на базі перетворювачів інформації з ваговою надлишковістю

Abstract

Magister is devoted to the development of digital recording and playback of high-precision analog signal from the DAC with weight redundancy. The use of such devices at this stage is important because it is necessary to keep in touch with analog computer equipment. In this work analyzes the possibility of building accurate system of collection and reproduction of information on the basis of inaccurate digital-to-analog converters by using weight redundancy, and existing methods for improving the linearity and performance of analog nodes. We construct a block diagram and algorithm of the system for collecting and reproduction of data, analysis of static and dynamic errors. Proposed to estimate the static characteristics of the CA transformation. Increases the accuracy of the system by introducing a dc amplifier, built on the principle of push-pull symmetric structures.
