The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM ....etc

Introduction

Basics of Audio Compression

Advances in digital audio technology are fueled by two sources: hardware developments and new signal processing techniques. When processors dissipated tens of watts of power and memory densities were on the order of kilobits per square inch, portable playback devices like an MP3 player were not possible. Now, however, power dissipation, memory densities, and processor speeds have improved by several orders of magnitude. Advancements in signal processing are exemplified by Internet broadcast applica ....etc

Abstract

An integrated photonic microwave bandpass filter has been demonstrated incorporating a coherently coupled microring resonator in low-loss polymers. The resonator was designed to have an extremely small bandwidth so that it could be used to selectively pass the optical signal carrying the microwave signal to attain efficient bandpass filtering. The demonstrated device may feature compact size, simple structure, stable operation, possible tuning via the thermooptic effect, and furthermore flexible integration with other electrical/opt ....etc

The average person has a small home, but a huge appetite for entertainment. All of us would want to zap video images from digital camcorders to our hard drives without tripping over the cables that connect them. As home entertainment systems become more sophisticated, u will have flat panel displays. You could hang them like paintings on your wall¦..Now who would want cables to dangle from those beauties?

So you think - big deal¦. We have Bluetooth and 802.11 wireless technologies to solve this problem. They do a dece ....etc

UWB is a wireless technology that transmits binary data”the 0s
and 1s that are the digital building blocks of modern information
systems. It uses low-energy and extremely short duration (in the order
of pico seconds) impulses or bursts of RF (radio frequency) energy over
a wide spectrum of frequencies, to transmit data over short to medium
distances, say about 15”100 m. It doesn™t use carrier wave
to transmit data.

Power line communications (PLC) or Broadband over Power Lines (BPL) allows transmission of data over power lines.Power line communications uses the RF signal sent over medium and low voltage AC power lines to allow end users to connect to the Internet. The RF signal is modulated with digital information that is converted by an interface in the home or small business into Ethernet compatible data.

To gain a good understanding of how PLC Works an excellent understanding of the Power Grid is required. Unlike telephony and it's ass ....etc
