Residential or occupational exposures to electric or magnetic fields have been reported to be associated with health problems, particularly cancer and reproductive mishaps. Misconceptions about these alleged effects continue to be published in the medical and scientific literature. Invalid statements relating to these effects are challenged in this paper. Case reports and studies dealing with e...

This contribution presents a new vision based remote control for interactive television (ViBReCIT) and DVD players. This device is easily and intuitively used due to its vision based pointing ability in combination with only two push buttons. The purpose of this remote control is to use a pointer based scheme for menu selections on the television screen. For this purpose a low-resolution, low-c...

establishing and operating private radio and television and its possible activity beside state radio and television is the selective method of administering radio and television in many countries worldwide. in legal system of iran, state run radio and television in article 44 of the constitution and interpretation of guardian council of mentioned article, establishing private radio and televisi...

This study presents the evaluation of digital video broadcasting-terrestrial second generation (DVB-T2) Television signal quality in Jos using Integrated Services Limited signal. The delivery remains problematic Nigeria due to attenuation and degradation between transmitter receiver station. is primarily environmental atmospheric perturbations prevalent along paths. research aim determine DVB-T...

Digital techniques have been used in sound programme production and transmission by some broadcasters for many years now, and more recently have become cheap enough to be introduced into the domestic consumer market, leading to wider public appreciation of high-quality sound, albeit via non-broadcast digital media. At the same time, there is rapidly growing congestion in the VHF/FM radio bands ...

In this paper the secrecy problem in the cognitive state-dependent interference channel is considered. In this scenario we have a primary and a cognitive transmitter-receiver pairs. The cognitive transmitter has the message of the primary sender as side information. In addition, the state of the channel is known at the cognitive encoder. Hence, the cognitive encoder uses this side information t...

In this paper, to investigate the effects of interference resulting from the standard setting of Block Edge Mask (BEM), assuming the use of LTE systems in the Digital Dividend, the minimum separation distances according to the size of guard band between DTV transmitter and LTE base station for a specific BEM are calculated.

We describe a UHF RFID reader which uses low cost off-the-shelf components such as MSP430 microcontroller and the TH7203x transmitter IC. The receiver circuit is based on envelope detector and analog data slicer. The design is very simple and can be used as an educational tool for academic

The FM band (87.5-108 MHz) is home to a large number of radio programmes, and is still the main means of radio broadcasting in Europe. However, the FM band is fully allocated and therefore cannot offer a basis for increased diversity in the radio broadcasting landscape, nor can it offer an increase in the coverage areas of the broadcasters already licensed. Local radio as well as community and ...
