METHOD OF DIGITAL-TO-ANALOGUE CONVERSION Russian patent published in 2013 - IPC H03M1/66 

FIELD: measurement equipment.

SUBSTANCE: in the method of digital-to-analogue conversion including production of an impulse signal, duration of the conversion cycle of which is defined by the capacity of the converted code, and duration of the information signal is proportional to the converted code, subsequent normalisation of the amplitude of the received signal and its filtration in the area of low frequencies, additionally, before filtration, the information signal is generated in the form of a sequence of pulses that are discretely-evenly arranged on the time axis in the range of the conversion cycle, with their duration multiple to the period of oscillations of the clock pulse generator, besides, the total duration of these impulses in the conversion cycle is proportionate to the converted code.

EFFECT: improved accuracy and reduction of conversion time.
