Abstract

FIELD: digital communication systems with pulse-code modulation. SUBSTANCE: method involves selection of measured time interval between edges of primary pulses of signals so that distance between edges corresponds to integer number of periods of linear frequency without preliminary processing. EFFECT: increased precision, increased functional capabilities.

Способ измерения фазового дрожания относится к области цифровых систем связи с импульсно-кодовой модуляцией, в частности к способам контроля этих систем. Цель изобретения - повышение точности измерения и расширение функциональных возможностей. Это достигается в предлагаемом способе за счет выбора измеряемого интервала времени между фронтами первичных импульсов сигнала, номинальный интервал времени между которыми соответствует целому числу периодов линейной частоты, в отличие от известных, где первичный сигнал вначале преобразуется с помощью ВТЧ.The method of measuring phase jitter relates to the field of digital communication systems with pulse-code modulation, in particular to methods for monitoring these systems. The purpose of the invention is improving the accuracy of measurement and expanding functionality. This is achieved in the proposed method by selecting the measured time interval between the edges of the primary pulses of the signal, the nominal time interval between which corresponds to an integer number of periods of linear frequency, in contrast to the known ones, where the primary signal is first converted using VHF.
