DLP Projector
Abstract
DLP Projector is an optical system driven by digital electronics. It s the only display solution that enables movie video projectors, televisions, home theater systems and business video projectors to create an entirely digital connection between a graphic or video source and the screen in front of you. At the heart of every DLP projection system is an optical semiconductor that manipulates light digitally known as the Digital Micromirror Device, or DLP chip which is a rectangular array of up to 2 million hinge- ....etc

Abstract:
Digital Light Processing is a way to project and display information. Based on the Digital Micro mirror Device (DMD) developed by Texas Instruments, DLP creates the final page link to display digital visual information. DLP technology is being provided as subsystems or engines to market leaders in the consumer, business, and professional segments of the projection display industry. In the same way the compact disc revolutionized the audio industry, DLP will revolutionize video projection. DLP has three key advantages over ....etc

Abstract:

A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels to mobile receivers in an environment with severe multipath delay and fading. Optimum combination of frequency and time diversity to guarantee robust performance in the mobile channel, with its multipath delay and frequency-selective fading effects. The system is based upon a dynamic single channel per carrier assignment of each stereo channel to many carriers. Inter symbol interference degradations caused by multipat ....etc

Digital-to-Analog Analog-to-Digital
Data Handling Systems
Both data about the physical world and control signals sent to interact with the physical world are typically analog or continuously varying quantities.
In order to use the power of digital electronics, one must convert from analog to digital form on the experimental measurement end and convert from digital to analog form on the control or output end of a laboratory system.
Digital-to-Analog Conversion
When data is in binary form, the 0's and 1's may be of s ....etc
