Digital Audio's Final Frontier-Class D Amplifier

Digital technology continues its march from media like CDs and DVDs toward your audio speakers. Today, amplifiers based on digital principles are already having a profound effect on equipment efficiency and size. They are also beginning to set the standard for sound quality.

An old idea, the Class D amplifier has taken on new life as equipment manufacturers and consumers redefine the musical experience to be as likely to occur in a car, on a perso ....etc

The High frequency attenuation in shielded distribution cable has been extensively studied. But in the case of solid dielectric cable, this has not been done. A solid dielectric cable has a bit more complex structure including the semiconducting “bedding” layers and a moisture barrier.high frequency loss is created by these sources.The purpose of these bedding layers is to seal the cable against moisture ingress and also accomodate for the thermal expansion of the cable. The cables studied here are the ones with a corrugated copper sheat ....etc

SYNOPSIS
The project name is Virtual Desktop. This project is for communicating different people from distance. We can chat with one another. Not only chatting options but also some useful options available here. There would be a free white space on the screen, if we draw anything on that space then a person on the other side can see it, vice versa. Whatever the diagram which we draw on the screen it will be displayed on the other personâ„¢s window. We can send the photo also through it. If we donâ„¢t want to chat with some specified u ....etc

CLASS-D AMPLIFIERS
Abstract
Class D amplifiers present us with a revolutionary solution, which would help us eliminate loss and distortions caused due to conversion of digital signals to analog while amplifying signals before transmitting it to speakers. This inchoate piece of knowledge could prove to detrimental in improving and redefining essence of sound and take it to a different realm.

This type of amplifiers do not require the use of D-A conversion and hence reduce the costs incurred for dev ....etc

Efficiency Improvement of WCDMA Base Station Transmitters using Class-F power amplifiers


Muthuswamy Venkataramani



(ABSTRACT)
Universal Mobile Telecommunications Systems (UMTS) is the preferred third generation (3G) communication standard for mobile communications and will provide worldwide coverage, a convenient software technology and very high data rate. The high data rate, especially, requires the use of bandwidth-efficient modulation schemes such as Quadrature Phase Shift Keying (QPSK). But ....etc
