ABSTRACT
The term echo cancellation is used in telephony to describe the process of removing echo from a voice communication in order to improve voice quality on a telephone call. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network.



Two sources of echo have primary relevance in telephony:
acoustic echo and
hybrid echo.
Echo cancellation involves first recognizing the originally transmitted signal that re-appe ....etc

Computer Memory Based on the Protein Bacteriorhodopsin


While magnetic and semi-conductor based information storage devices have been in use since the middle 1950's, today's computers and volumes of information require increasingly more efficient and faster methods of storing data. While the speed of integrated circuit random access memory (RAM) has increased steadily over the past ten to fifteen years, the limits of these systems are rapidly approaching. In response to the rapidly changing face of computing and demand for

An Introduction To Real Time Linux
Chapter 1. Introduction
GNU/Linux has conquered the minds and imagination of
computer enthusiasts throughout the world because it
is open source and adaptable to different hardware and
computing problems. As a general purpose Operating
System, however, the Linux kernel optimises average
performance and is not that appropriate for real-time
applications as such. For this reason there are some groups
sp ....etc

ABSTRACT
Voice (and fax) service over cable networks is known as cable-based Internet Protocol (IP) telephony. Cable based IP telephony holds the promise of simplified and consolidated communication services provided by a single carrier at a lower cost than consumers currently to pay to separate Internet, television and telephony service providers. Cable operators have already worked through the technical challenges of providing Internet service and optimizing the existing bandwidth in their cable plants to deliver high ....etc

ABSTRACT
A computer cluster is a group of loosely coupled computers that work together closely so that in many respects it can be viewed as though it were a single computer. Clusters are commonly connected through fast local area networks. Clusters are usually deployed to improve speed and/or reliability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or reliability. Cluster computing has emerged as a result of convergence of several trends i ....etc

ABSTRACT
In January of 2000, Transmeta Corporation introduced the Crusoe processors, an x86-compatible family of solutions that combines strong performance with remarkably low power consumption. As might be expected, a new technology for designing and implementing microprocessors underlies the development of these products. As might not be expected, the new technology is fundamentally software-based: the power savings come from replacing large numbers of transistors with software.
The Crusoe ....etc

ABSTRACT

Switching products technologies ranges from traditional Electro Mechanical Relays (EMR) and reed relays to semiconductor switches made of silicon or GaAs materials. A new type of device is currently getting to commercialization. The first sales of RF MEMS switches outside DOD programs have been realized by Teravicta in 2006. The achievements of RadantMEMS in USA DOD programs, the first commercial product sales from Teravicta in 2006 and the 4 other competitors (MEW, XCOMwirel ....etc

Interface your PC to an RC Radio
Recently I built a couple of projects where I interfaced a PlayStation controller to a microcontroller. While this works fine in many situations there are times when you want to use an RC radio for its extended range or reliability. In this article we are going to create a very accurate and reliable interface to any RC radio with up to 6 channels. To perform this interface we will create a Coprocessor using a microcontroller. Once complete we can then connect other devices or even a PC to this interface ....etc
