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 personal stereo, or on an airplane as in a living room. For most consumers today, portability and ....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

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc

Abstract

A human's ability to perform physical tasks is limited by physical strength, not by intelligence. We define extenders as a class of robot manipulators worn by humans to augment human mechanical strength, while the wearer's intellect remains the central control system for manipulating the extender. Our research objective is to determine the ground rules for the design and control of robotic systems worn by humans through the design, construction, and control of several prototype experimental direct-drive/non-direct-drive multi-de ....etc
