Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

Abstract:
The most common signage for people who are blind is restricted to tactile displays. This requires persons to be at the location of the signs before they can identify the information it bears. Using such signage as an aid in locating and traveling to a telephone booth, bus stop, elevator, public electronic terminal, building entrance or exit, leads to the paradoxical effect of having to already be there before one knows where it is. in addition to the problem of locating specific travel goals, very often blind travelers are una ....etc

ABSTRACT
This paper describes the implementation of a low cost PC - based logic system suitable for either
small scale chip or printed circuit board testing. The system incorporates a flexible graphical user interface
(GUI) which permits users with little or no programming expertise to generate tests and operate the system
quickly and efficiently. System cost is of the order of £1,000 which makes it very attractive to SME's.

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
