Основні переваги застосування високорозрядних ЦАП з ваговою надлишковістю у системах прямого цифрового синтезу

Abstract

It is shown that the construction of direct digital synthesis systems Direct Digital Synthesizer with the use of a DAC based on redundant positional number systems allows not only to increase the total accuracy and reliability due to the correction of the discharge weights, but also to reduce the noise level due to statistical averaging of several consecutively used code equivalents of the output signal.
