THE METHODOLOGY OF CIRCUIT CONSTRUCTION OF THE ANALOG VALUE CONVERTER IN THE TIMEFRAME

Измерение, мониторинг, управление, контроль, 2023
Background. Most modern digital voltmeters use an analog-to-digital converter (ADC) of the time-pulse type with two-stage integration, which takes place in two stages – integration and counting.

Lumped time-delay compensation scheme for coding synchronization in the nonlinear spectral quantization-based all-optical analog-to-digital conversion

, 2013
In this paper, we propose a novel lumped time-delay compensation scheme for the all-optical analog-to-digital conversion based on soliton self-frequency shift and optical interconnection techniques.
