Predictive analog-digital-conversion in fiber optics communication

2014 IEEE 28th Convention of Electrical & Electronics Engineers in Israel (IEEEI), 2014
Advances in digital hardware had enabled a new generation of fiber optics communication receivers. Extensive digital-signal-processing (DSP) allows compensating for channel impairments and, in turn, scaling up in data rate. One of the main challenges in modern receivers is implementing a high-rate, high-precision analog-to-digital-converter (ADC) that ...

Dynamic error in analog-digital conversion

Measurement Techniques, 1968
A method of determining the error characteristics for the analog-digital conversion of a time-varying quantity has been investigated which takes into account the inherent instrumental errors of the converter and the specific errors of the analog-digital conversion method.

Multirate analog-digital systems for signal processing and conversion

Proceedings of the IEEE, 1997
Systems containing both analog and digital functions have been investigated with the purpose of realizing mixed-signal integrated circuits with higher levels of functionality and integration. In most cases, such mixed-signal systems are inherently multirate because of the different sampling rates employed at various stages of the system.

Analog/digital map conversion and cartographic information content changes

SPIE Proceedings, 2007
The mutual conversion between analog map and digital map is two main contents of the study on digital mapping, which is the production of paper map and spatial data. The visualization of spatial data is the common problem that the spatial data application system confronted, so it is practically meaningful to study the mutual conversion between analog

Energy relationships of processes linked by analog-digital conversion

Radiophysics and Quantum Electronics, 1991
A class of analog-digital conversions that are invariant with respect to the energy characteristics of the processes being converted is shown. This means that the energy characteristics of a continuous process and of the pulsed process obtained from the continuous process by analog-to-digital conversion agree exactly, regardless of the relationship ...

A successive double-bit approximation technique for analog/digital conversion

IEEE Transactions on Circuits and Systems, 1990
To achieve a higher conversion speed in an analog-to-digital converter (ADC), a modification to the successive approximation technique is proposed. In this, 2 b of digital output are approximated simultaneously instead of 1 b at a time. Simulations and layout of an A/D converter based on the proposed technique have shown an improvement in the ...

Tx Leakage Impact on Analog-Digital Conversion in Zero-IF Receivers

2009 IEEE 70th Vehicular Technology Conference Fall, 2009
Transmitter Leakage has a significant impact on the system performance in mobile devices using zero-IF receivers and thus requires a suitable compensation. In contrast to analog approaches, digital Tx Leakage compensation approaches can easily be reconfigured and therefore are highly attractive for future mobile devices, using software defined radios ...

Nonlinear distortions caused by sigma‒delta analog-digital conversion of signals

Journal of Communications Technology and Electronics, 2017
With the use of a linear approximation, the quantizer characteristics are defined by the stability conditions of the discrete models of the first- and second-order sigma‒delta analog-to-digital converters. The processes occurring in the nonlinear converter models are discussed at an arbitrary amount of digit positions in the representation of numbers ...

Synthesis of the analog-digital conversion channel in automatic railroad systems

Russian Electrical Engineering, 2012
Synthesis of the analog-digital conversion channel is considered in microprocessor systems responsible for the protection, diagnostics, and monitoring of the basic power equipment in tractional substations for electrified railroads. The influence of various factors on the error and noise stability of the channel is investigated.
