High-Precision Techniques of Analog Input Unit for Advanced Digital Protection Relay

Digital Communications for Relay Protection

Electric utilities are expanding communications infrastructure due to increased need for information. Due to performance, price, and technological advances, digital communication systems are frequently chosen as this multiple user data network. This two-part paper describes the application of digital communication in power system protection. Part 1 describes the digital communications architect...

Low-cost testing of high-precision analog-to-digital converters

Advanced Matching Techniques for High Precision Surface and Terrain Models

Image matching is currently gaining increased interest in the photogrammetric community to provide accurate and very dense point clouds for Digital Elevelvation Models (DEMs). Besides the traditional Digital Terrain Models (DTMs) the focus is more and more on Digital Surface Models (DSMs). It can be seen as an alternative technique or even competition to airboren laserscanning (LIDAR) which is ...

Digital Background Calibration Techniques for High-resolution, Wide Bandwidth Analog-to-digital Converters

Analysis of Signal Integrity for High Precision Digital-to-Analog Conversion Circuit

In order to improve the accuracy of the digital to analog conversion (DAC), the reflection and crosstalk problems of the signal transmission process were studied in this paper. The Hyperlynx software was used for the simulation study of reflection and crosstalk problems of the master clock signal in the DAC circuit. Source end cascading termination resistor and remote end termination resistor a...
