Design, Construction and Testing of a Low Energy Digital Frequency Modulation (FM) Transmitter
International Journal of Scientific & Engineering Research Volume 11, Issue 1, January-2020 534 ISSN 2229-5518 Design, Construction and Testing of a Low Energy Digital Frequency Modulation (FM) Transmitter JP. C. Mbagwu, F.M.Ezike, J.O.Ozuomba Abstract---- A rapidly growing demand for the use of Frequency Modulation (FM) transmitter exists within institutions and individuals. The FM transmitters are however a complex equipment demanding high power supply, high voltage system design, critical maintenance and exorbitant price. These problems of the transmitter constitute major impediments to institutions and individuals that may wish to adopt radio broadcast as means of electronic media. This study was therefore carried out to design and construct an FM transmitter that is of low cost, and simple in maintenance, efficient in use and yet operating on low power supply. The FM transmitter is designed to be received at a range of about 100metres in free air. The transmitter has a capacitor microphone which picks up very weak sound signals, a transistor, resistors, inductor, and capacitors. The design procedure involves the modification of an output of the transmitter. Based on the procedures adopted and the tests carried out, the specific findings include a range of 102.2MHz of transmission from a 9V DC battery. The work indicated that the practical frequency modulated (FM) transmitter requiring a low power can be designed and constructed. Index Terms----Frequency Modulation, FM Transmitter, Radio Broadcast, Antenna. 1.0 INTRODUCTION combined in one unit are called a transceiver. The In electronics and telecommunication, a transmitter term transmitter is often abbreviated ‘‘XMTR’’ or or radio transmitter is an electronic device which ‘‘TX’’ in technical documents. -
Internet Freedom in China: U.S. Government Activity, Private Sector Initiatives, and Issues of Congressional Interest
Internet Freedom in China: U.S. Government Activity, Private Sector Initiatives, and Issues of Congressional Interest Patricia Moloney Figliola Specialist in Internet and Telecommunications Policy May 18, 2018 Congressional Research Service 7-5700 www.crs.gov R45200 Internet Freedom in China: U.S. Government and Private Sector Activity Summary By the end of 2017, the People’s Republic of China (PRC) had the world’s largest number of internet users, estimated at over 750 million people. At the same time, the country has one of the most sophisticated and aggressive internet censorship and control regimes in the world. PRC officials have argued that internet controls are necessary for social stability, and intended to protect and strengthen Chinese culture. However, in its 2017 Annual Report, Reporters Without Borders (Reporters Sans Frontières, RSF) called China the “world’s biggest prison for journalists” and warned that the country “continues to improve its arsenal of measures for persecuting journalists and bloggers.” China ranks 176th out of 180 countries in RSF’s 2017 World Press Freedom Index, surpassed only by Turkmenistan, Eritrea, and North Korea in the lack of press freedom. At the end of 2017, RSF asserted that China was holding 52 journalists and bloggers in prison. The PRC government employs a variety of methods to control online content and expression, including website blocking and keyword filtering; regulating and monitoring internet service providers; censoring social media; and arresting “cyber dissidents” and bloggers who broach sensitive social or political issues. The government also monitors the popular mobile app WeChat. WeChat began as a secure messaging app, similar to WhatsApp, but it is now used for much more than just messaging and calling, such as mobile payments, and all the data shared through the app is also shared with the Chinese government. -

MASS MEDIA AND THE TRANSFORMATION OF AMERICAN POLITICS I. INTRODUCTION The importance of the mass media1 in today's society cannot be over- estimated. Especially in the arena of policy-making, the media's influ- ence has helped shape the development of American government. To more fully understand the political decision-making process in this coun- try it is necessary to understand the media's role in the performance of political officials and institutions. The significance of the media's influ- ence was expressed by Aleksandr Solzhenitsyn: "The Press has become the greatest power within Western countries, more powerful than the legislature, the executive, and the judiciary. One would then like to ask: '2 By what law has it been elected and to whom is it responsible?" The importance of the media's power and influence can only be fully appreciated through a complete understanding of who or what the media are. -

Abstract When Netflix launched in April 1998, Internet video was in its infancy. Eighteen years later, Netflix has developed into the first truly global Internet TV network. Many books have been written about the five broadcast networks – NBC, CBS, ABC, Fox, and the CW – and many about the major cable networks – HBO, CNN, MTV, Nickelodeon, just to name a few – and this is the fitting time to undertake a detailed analysis of how Netflix, as the preeminent Internet TV networks, has come to be. This book, then, combines historical, industrial, and textual analysis to investigate, contextualize, and historicize Netflix's development as an Internet TV network. The book is split into four chapters. The first explores the ways in which Netflix's development during its early years a DVD-by-mail company – 1998-2007, a period I am calling "Netflix as Rental Company" – lay the foundations for the company's future iterations and successes. During this period, Netflix adapted DVD distribution to the Internet, revolutionizing the way viewers receive, watch, and choose content, and built a brand reputation on consumer-centric innovation. -
